Hello and welcome. Thanks for posting.
We’re going to need a lot more information than this. Not everything is obvious in the log. What version of kit are you using? What were you doing when it crashed? Rendering? Simulating? Lighting? What other software do you have open at the same time? You mentioned 3dsmax. Was that open at the same time? Were you trying to connect them?
Ideally if it’s crashing all the time, can you get a video of crashing with a description about you were doing at the time. The app should be very stable. If it is crashing all the time it is either hardware, drivers, or workflow. So give me as much detail as possible.
Let me analyze the log and get back to you.
Hi,
Thank you very much for your message!
I’m using Omniverse Kit SDK version 108.0. Please have a look at videos I recorded while using USD composer and it crashing:

Please have a look at latest logs.
Also some screenshots of my settings here: https://docs.google.com/document/d/11rwiXNFj18CsTAiGiHKXqVdkgnj0QGqGYQnjvzmR6b4/edit?usp=sharing
Please, would you let me know what else I can do to fix this issue. Thank you…
Kind regards,
Zibi

Thanks for this detail. I can see the logs and the video. It does not offer much detail. Just a generic GPU crash. I can try to look up the crash report at this end.
Have you tried updating your video drivers?
Make sure you have no other applications open until we identify the issue
Are you running at super high resolution with scaling on ? It looks like you are running 4k with scaling set to 200-250%? I would reset it back to 100% for a moment to test.
Can you try starting over fresh? Deleting the kit-app-template folder, and ov folder in your temp drive and even the repo folder in your C:.root?
“C:\packman-repo”
“C:\kit-app-template”
“C:\Users\user\AppData\Local\ov”
Hi Richard, thanks so much for your great effort to support me.
Yes, I have performed extensive troubleshooting with my video drivers. I first did a clean installation of the latest NVIDIA Studio driver, but the crashes continued.
I then attempted to downgrade to the officially recommended stable Studio driver for Omniverse (537.58) but the installer failed because it was not compatible with my version of Windows 11. I have now installed the downgraded version of another recent Production Branch driver (576.80)
But the crashes continue.
I have also reset the resolution to 100% at 1920x1200 but the crashes continue.
Then I started over fresh (deleted kit-app-template folder, ov folder and repo folder, installed kit-app again), still no luck.
And no other applications running in parallel - also tested… Still no luck…
The next thing we are going to need is the “dump file”. So this is the file it writes out when composer crashes. It will crash and in the logs before it exits it will point to a dump zip file. We need to grab that and analyze it.
It is JUST this latest kit 108 ? Can you try an older kit 106.5 version ? Or even Isaac Sim 5.0 ?
Can you make sure you flush your logs and do one more run and get my a ‘clean’ log and a dump file, showing me more of the issue. The one you posted does not really make a lot of sense. It is saying it took 3.5 mins to try to start the app and then crashed without ever starting. It was constantly downloading extensions. That makes no sense. Did you “build” the app before launching? It should have already done that.
For example, we need this C:/Users/zibi/AppData/Local/ov/data/Kit/My USD Composer/0.105182bb8-94ce-4821-b528-b14936346f59.dmp.zip
I have heard back from the engineers. Right now, we are not sure what is happening. But we do know its something to do with “omni.ui.scene”, Gestures class
C++ code calls a class that is inherited in python. The crash happens in the bindings, that would likely mean some of the objects are invalid state.
I will respond to you asap. Thank you!
Any update?
Hi Richard,
sincere apologies, it’s been extremely busy weeks… Finally I wiped my whole laptop and installed Windows, then the Omniverse Kit. Still same issues, 108 crashes (logs attached). I’ve been testing 106.5 and it failes to launch (attached as well). I am exhausted after hours spent trying to fix this, but maybe you have an idea in the meantime after looking at the files..? Thank you very very much for all your help.

Also not sure if this is of any help, some screenshots of crashes are here: crashscreenshots - Google Docs
Hmm, very strange. I sent you a DM so I can investigate further.
It is missing loads and loads of extensions that should not be enabled. Are you just building a basic template and starting it, or are you trying to load it many non standard extensions? For example it is looking for the curve extension. That is not standard. That should not be enabled. Are you adding that it manually?
You need to just try to build a basic level template. Nothing extra.

Also are you trying to do this through a python system / Environment? That could be a factor. Just build this in a basic Windows CMD panel.
This is what Perplexity is saying
The primary cause of this Omniverse Kit crash is a failure to resolve extension dependencies, especially for several "omni.*" extensions (such as omni.anim.curve.core, omni.anim.curve.ui, omni.anim.curveeditor, omni.anim.shared.core, omni.anim.timesamplesplayer, omni.anim.timeline, among many others). The crash log reveals multiple "Can't find extension to satisfy dependency" errors, meaning the required extension versions either cannot be found in the local registry or are present but platform-incompatible.
## Key Issues Identified
* **Missing/Platform-Incompatible Extensions:** The log lists many extensions with required versions that are either missing or incompatible with the current platform (such as Windows or the Python environment being used). This prevents the application from loading necessary plugins and features.
* **Dependency Solver Failure:** The main plugin manager (omni.ext.plugin) cannot resolve or install critical dependencies. This triggers the app to exit during startup, explicitly stating "Exiting app because of dependency solver failure...".
* **Python Environment Misconfiguration:** There's an additional error where the Python environment path (PYTHONHOME) could not be set because the expected directory doesn't exist. This may further interfere with plugin startup.
* **Crash Report and Diagnostics:** The log shows the crash reporter is triggered (carb.crashreporter-breakpad.plugin), followed by the application generating and uploading crash dumps for diagnostics. The actual crash seems to occur almost instantly after startup, as the "UptimeSeconds" logged is 1, and the crash backtrace points mostly to internal kit plugins and standard Windows DLLs.
## What This Means
* The Omniverse Kit experience ("My USD Composer") failed to start because critical extension dependencies were not available or were platform-incompatible.
* The build and launch process itself completed, but when the main application attempted to load necessary extensions, it found a long chain of missing or incompatible library and plugin versions.
* There are also signs of misconfigured PowerShell commands while attempting to clear local caches or folders, which could indicate further automation or environment setup problems, but these are secondary to the plugin dependency failures.
## Recommended Actions
* Ensure the extension registry has all required versions of dependencies and they are compatible with the platform (OS and Python version).
* Check and fix local Python environment configuration (ensure the pythonHome directory exists and paths are correct).
* Consider cleaning and updating extension caches, then relaunching.
* If deploying custom extensions or builds, double-check compatibility flags and build targets.
The crash is not due to a code or run-time bug, but a startup/configuration failure caused by unresolved dependencies and platform mismatches.
Our engineers are looking at this now. The crash log is saying that it is something to do with a crash in python in [ScriptingPython.cpp:302]
Thanks so much Richard and to the engineers for looking into it.
They have said it is nothing to do with your RTX video drivers or the GPU. It is something else. Can you try to build the template OUTSIDE of any VSCode Environment.
Ok, lets try something here. Please wipe all OV off your computer and try to download and install the FULL KIT package from our NGC link. You will need to register a free developer account to access this, at www.ngc.nvidia.com
GPU-optimized AI, Machine Learning, & HPC Software | NVIDIA NGC
Once you download the 1.55GB zip file and unzip it (I would use 7zip for this), please just run “omni.app.editor.base.bat” in the main root folder. That should work fine.
Hi Richard, I recorded the process for you here:

Hi Richard,
not sure if this is helpful but I ran the Isaac Sim Compatibility Checker, the screenshot I got seemed OK, then I ran the Test Kit, the comment says the “Kit app started correctly. Test execution completed”, but in the terminal I’ve seen a message, that might be interesting for you? I attach the txt file with it + the log.

Thoughts?
