I tried to run minecraft on the 1.17 version and, no matter how many times I reinstall the version files or reinstall the whole .minecraft folder, it's the same evey time.

The loading screen for minecraft now says Moj Stu instead of Mojang Studio, every UI is glitched and for some reason when you spawn a mob, its textures will overlap with other already spawned mobs.

This doesn't happen with other versions, only with the new 1.17 one.
