SolvedCSGO Hold Left Alt

Whenever I use CSGO hacks, I tend to only use radar and trigger but since I don't like using constant trigger I normally use the Left Alt key as a Hold key for triggers. After a few months of not playing with cheats, I decided to play with it again cause why not and for some reason my Left Alt key no longer works. The trigger still works but my mouse cannot move. This is the same result for every public hack out there that has Left Alt key to hold for trigger or aim. It seems like whenever I hold down Left Alt, my mouse would stay stationary and I can't look up, down, left, or right. Did Valve implement a system where if you hold Left Alt, it stops mouse movement?
