As others have said, did you try to rebuild the database? Just to see if something changes.
The fact that only trophy videos are affected is peculiar, makes me think of a software problem rather than an hardware one. Then again, if it was indeed software, it would be much more widespread between users.
Something is wrong with your console, that's for sure.
Yes, I tried, but the videos are corrupted yet, the one different thing, is when I rebuilt I lose the thumbnail, because rebuilding is removing old thumbnails and PS5 can’t extract a new thumbnail from the video.
Maybe I will test a factory reset soon.
Edit: I just remember I installed wasteland 3 the last Sunday. I will test again, because i bought the game around the first time I got corrupted on December, but don’t remember when I installed for first time.
