I would need a little more information. Is this running the new Kit App Template 106.0.2? Have you previously made it and run it successfully? It seems that something has changed. Have you accidently deleted a required library or directory? Did you change your video drivers?

I would focus in on “HydraTextureFactory” and “omni.ext._impl.custom_importer” as two areas. It looks like something has been removed, deleted, etc. You could try deleting the app build files and rebuilding it from your kit template.

Thank you for your answer. I was using it for days, but suddenly it doesnt work anymore. I changed nothing i deinstall it and install it new, but i have the same issues. It is the Omniverse Kit 106.0.2.
Can you show me a tutorial or something else i dont know how to change the files.

Well if I were honest, you are using a pretty old version of the KAT. You need to be on the very latest, the KAT 106.3. So I would just delete that whole template and the entire development folder, and start fresh with the 106.3 template from GitHub. GitHub - NVIDIA-Omniverse/kit-app-template: Omniverse Kit App Template

5

Do you have a tutorial how i can deinstall everything in a clear way?

6

There is no special way with this. It is literally just a simple download and run system. Therefore you would just use normal Windows Explorer to delete the entire Omniverse Kit App Template folder from the root and re-build. If you have a custom app that you would want to “upgrade” to the latest version of kit then there would be a special upgrade path.

Okay i will try it at the weekend and give you an answer.

8

I am not able to fix this problem, what is KAT and how i can implement it to my system

9

I reinstalled it and it worked, but i dont know why.
