So I lent my account to my cousin, and he changed my binds a bit which I thought would be no problem. well, now whenever I try and toggle mute in discord it just mutes me altogether. To which I can't unmute and go alt tab to unmute It just doesn't work. The game for some reason takes full priority of my pc. It doesn't let me use my extra mouse buttons as key binds anymore either.

If anyone has had something similar or knows how to fix this please let me know.
