Gears of War 2 Constantly Crashing after playing local coop

I need to fix this, I literately can’t even play on my profile anymore.

Been a problem for years now, no way to fix as far as I know. Made a new dummy account to try and play through COOP again but that ended up with the same error. Single player works fine

There is a fix on YouTube but doesn’t always work.
Only problem is when it does as soon as you play splitscreen again it corrupts your profile again and back to square one.
