First, backup your whole .minecraft folder so you're able to reproduce the issue in case you accidentally fix it without knowing what you did.

Remove OF. If it happens without OF, then there's no reason to further complicate things by having it installed.
Fast Render is not supported anyway.

Which versions were previously working? Are they still working? Can you narrow down which specific version broke it for you?

the latest version

whelp anyway i removed optifine and now it works thenks anyway :)
