file has an unsupported compression type - mp4 H.264

Hello! I know that this question has been asked before, but I can't seem to find a way to solve my issue because I don't understand every single thing people mention in help pages. So my problem is that I get "the file has an unsupported compression type" error message whenever I try to import an mp4 file. I'm not sure why this is happening, because I always do the same thing (download videos from Youtube to use in my project), and about a month ago this error message has popped up. And well, I have no idea what to do about it. I tried to clean caches, update my windows and drivers, I even unstalled Premiere Pro, but nothing seems to help.

People recommended to check information about the mp4 file, so I attached a picture of that as well. If anything seems weird, please let me know, because I'm not sure what to look for. mp3 files are fine, but all mp4 files just won't import. Editing videos is just a hobby for me, but I want Premiere to work obviously. Thank you in advance!
