Hello @blazys.ignas! I let the Audio2Face team know about this post. Can you let us know the steps you took that created this error? Also, if you are able, can you send me your logs?

Hi @blazys.ignas. The team needs your full log file to figure out where the error occurred.

It was suggested that you might be experiencing a the same Windows 11 problem there: Windows 11 (wmic.exe is removed) If so, I posted a workaround while we wait for our dev team to fix the problem.

Hi @blazys.ignas ,
Are you able to provide the repro steps?
When you create the a2f pipeline? do you have any object selected in the scene?
I assume the default example scene with Mark head is working fine for you?
Thank you

Hey guys, I got this error while mixing and matching the templates. By doing stuff manually with the startup head it works flawlessly.
