This glich has happened to me in the aftermath of meeting moon and hibernating I simply quit the game when I hibernated.
(I did have mods on several of them but they were turned off)
Then the next day when i returned to play the game and go into monk's campaign the controls just whouldnt work I whould aggressively spam the arrow keys the pause key any key that whould do anything but nothing whould work.
Only the mouse whould work that's how I actually in the first place was able to go into monk's campaign.
Also I did check if it was just my keyboard and it is working fine outside of the game.
