Hello @sinisa! Let me know if this is correct. It sounds like you installed the new version of Audio2Face and now the older versions are no longer working. You are also not able to export any blendshapes.
So I have a couple of suggestions for when I run into this issue.
- Make sure you have the latest GPU Driver.
- Then try running the Omniverse Cleanup Tool.
- Then restart your computer.
Let me know if this cleans up the problem! If not, send me a copy of your logs from here: C:\Users\<USERNAME>\.nvidia-omniverse\logs\Kit\Audio2Face and include any new details that may help us troubleshoot the issue!
