After Effects imported footage always black and not playable

[Paul27241698x2kk]

Hi! I am having this problem since a few days that whenever I import ANY kind of footage or jpeg sequence (I tried all nothing works) the preview is just black and I can't press play. 

It happens on all versions even on the Beta version of AE. I reinstalled multiple times into all kinds of versions.

I work on an Apple M1 Mac OS Ventura, 16GB

Please help! I have tried everything I could possibly think of and even after scanning through the internet for ages i can't find this problem anywhere else...

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the After Effects forum so that proper help can be offered.
