[2021] [Bug/Glitch]My dpi in game too slow and game tabs me out

Hello im facing an issue when using my mouse ingame it feels super slow even tho i havent changed anything since the start of the week every thing was fine but yesterday i was playing aimlabs and my dpi and sens where fine but when i loaded terrorist hunt my sens where super slow i trieded a different mouse and the problem still there. I have reinstalled the game updated my drivers and reinstaled the drivers from my gpro but the problem is there also the game every time I open the ingame files when switching back to the game it tabs me out and freezes i tried opening my game throug uplay and steam/vulkan and nothing works. I played a different game to see if the problem was there but everything was fine so i think is something in r6. Also my dpi is 800 sens 18-18 and when i ads it feels worst
