Hello GreenRex7,
I'm Jin, a fellow Windows 10 user and an independent advisor.
The shortcut CTRL+SHIFT+Q is not a native Windows 10 shortcut.
Perhaps are you using a 3rd party app or a software for you keyboard that let's you modify certain shortcuts? If that would be the case, access this software and look for this shortcut and have it changed.
Also, does this only happens in the game that you are playing? If yes, open the Settings of your game and you should look for keyboard shortcuts or like and modify it from there.
Kind regards.
