Skins show up on screen ingame

Every time i join a server in any version (1.16 - 1.16.5), i get Minecraft skincodes on my screen, it blocks my view of the game, it doesn't matter if i press escape or go to main screen, the skincodes still stay and blocks my view.

I have deleted minecraft and installed it again, but it didnt help, please help!

1. I open Minecraft from the launcher.
2. When its done loading, i go to multiplayer and join a server.
3. Then when i have joined, my screen looks like the attached screenshots.

I have now added the crash report, i hope it helps.

Edit: I think i fixed it, using a drastic method. I went to the appdata folder and completely deleted the ".minecraft" folder, making it start totally anew. I hope you can find another solution, because i lost everything. For the better or worse, i dont quite know.

Edit 2: it only worked for a little while, before it started happening again, so it was only a temporary solution.
