Celluloid and VLC does not play anymore video, the sound is fine but the video is black, (Celluloid won't even start when I double on a video, I just got a spinning wheel for a while and nothing is happening)
This happens only on my account/session, on the others accounts (my kids) all players work just fine.
I started VLC in terminal with "vlc -vvv" and I get this
I have no idea what's happening
I'm on Ubuntu-MATE 20.04.5
