I think there’s an issue with uploading new avatars at the moment. I tried to use a new avatar and it just says “upload of file failed” so I used a link instead and it said “invalid file,” which it isn’t. I then deleted my old avatar and tried to reupload it to make sure it wasn’t a faulty avatar file for my new one, but it said the same thing.
I don’t know if you guys are aware of it, just wanted to bring it up.
Edit: It was most likely a glitch, it’s working fine now!
