what's your os-system? seems like an issue with either mediapipe or opencv package.

also, what's in the /tmp/blender.crash.txt file.

I think this issue is related to opencv, you probably got to manual install dependencies. At first, it would be good to gather some informations about your system - check the docs to do so (debian linux requires globally installed dependencies so conflicts just happen)...

Also, consider to refer to this issue: #118 Installing opencv via the local package manager may be the way to go

[Desagiato]

I have installed all the dependency manually and now i have this error,

I've install opencv manually from ubuntu packagemanager and it start to work, thank you so much

Glad it worked out, I'll reference this in the linux thread #129 and close it down
