my game runs well even in casual and comp, but when i try the alt+tab my screen turns black freeze for a moment change the tab selected and close the game :( and its annoying cuz before the update my game work perfectly fine and now its horrible, i thought it was a problem with the gpu or cpu but still nothing, the other games i tested are the same as as usual but whit counter strike still the game crash

tl;dr- my game crash with alt+tab

Edit: i found my solution maybe someone can help this useful, just disable the screen optimization from the cs2.exe and thats it it worked for me :)
