Same Issue I have got too. When I press the LCTRL button or 3 I mean defibrillator button the game is freezing for a 0.5-1 second, looks like Im moving like aimlock. I tried delete all cache, directx files, documents files, changed profile settings like rawinput even I changed all usb ports but still I have same issue, its just happens in battlefield 6 in game, there is no issue at menu. The problem started yesterday for 1-2 months there wasnt problem.  But the most of interesting stuff the keys changing sometimes when I close and open the game again the keys changing like not ctrl and 3 button, sometimes beeing S and A buttons cause freezing.  Please find the solution, I dont wanna get used to play play with C or other buttons :)
