Every Game i build crashes on startup but works in the Editor

Hello, Like the title says any Game i try to make suddenly doesn't work :/ everything i compiled a week ago works fine, but now all of a sudden when i compile a game it just imidietly crahses "does not respond" and has to be "force-closed" by task manager clicking on X doesn't work It really doesn't matter which project i try to compile or if its x86 oder x64 development build or not always happens i already tried to reinstall unity and create a new project where i dont even import any assets it was just a fresh project with nothing in it but a scene with a camera thats all... still happens also happens to all projects i already have.... In the Editor everything is fine and works without any errors not even yellow ones... does unity use any third party libraries that i may have accidently deleted or something like that? or could "avast antivirus" interfere with it? i already have that antivirus for months though... I appreciate any help ! thanks in advance!
