After Effects freezes when starting up on initialising Media Core

I hope someone could help because I'm at a loss with this problem.

I had several versions of after effects installed (23/24/25). I was working in 25, all went well and suddenly there was a crash. Since that moment I'm not able anymore to open any of these AE versions anymore.

When opening AE it freezes on "Initializing Media Core", it hangs and that's it.

Things I tried so far:

- removed all third party plugins

- removed all files in the Library/Application Support/Adobe/Common map

- uninstalled andn reinstalled all AE

- even did the total Adobe clean up and installed everything again

- but the problems is still there

Needless to say this is really frustrating and stressfull because I have projects to deliver. I am a user of Adobe and after effects since 2001 (!) now, and I never experienced such a severe crash problem as this one. Adobe how on earth is this posssibe.

So far my complaint, I hope someone can help me.

I'm on Mac, M1, 15.1.1 (Sequoia). Updated a few days ago, maybe that causes the problem?)

This is where it freezes:

Last log message was: <70496> <AppDirs> <5> Required Dir = /Applications/Adobe After Effects 2024/Adobe After Effects 2024.app/Contents/Required

Hope anyone can give me advise!
