NSight Graphics crashes on startup. (it’s a standalone app)

[codevania]

Hello,

As soon as I run NSight Graphics, it crashes immediately.
This issue occurs in both versions 2025.1 and 2025.2.
Version 2023.4.1 runs, but while the Unreal Engine launch parameter -dxd11 works, -dxd12 does not.
please help…

The crash screen is shown below. (versions 2025.1 and 2025.2)

You can download dump file below. (versions 2025.1)

Hi codevania,

Thank you for using Nsight Graphics and providing your feedback. We are sorry for any inconvenience you have encountered.

Are there any special to your Unreal Engine sample? We did some tests on the UE public samples before release. On the other hand, could you please provide your detail steps to reproduce the crash?

Thanks
An

Hi~ AYan. Thank you for reply.

Simply run NSight 2025.1 and 2025.2 it crashes after splash image.
Where can I get log files? I couldn’t find them.

When I run NSight 2023.4.1, the failure reproduction steps are as follows.

I tried rebuilding ShaderCompilerWorker as mentioned in the error dialog, but the result was the same

Hi codevania,

Simply run NSight 2025.1 and 2025.2 it crashes after splash image.
Where can I get log files? I couldn’t find them.

That’s weird. I am not sure what caused this, could you delete this folder and give it another try? Remove all files in %APPData%\NVIDIA Corporation (Please backup these files at first), and run Nsight Graphics again.

When I run NSight 2023.4.1, the failure reproduction steps are as follows.

I can run the official UE5.5 editor (downloaded from EPIC launcher) with default FPS template uproject on Nsight 2025.1 and 2025.2 smoothly. Could you take a try on the public build of UE?

Thanks
An
