Valorant keeps crashing even thought i took my pc to a shop for full diagnostics, I just did a complete windows refresh from a usb stick and redownloaded it multiple times please help i dont want to sell my pc. I also know its a vanguard issue cause error codes -81 and 1067 pop up and other games that use good anti cheat also crash like easy anti cheat. Also i keep getting black screens and it says what failed: vgc.sys
