Hello,
I came across this bug many times while playing the game, last time was right after I tried to record using windows+G
right after that, the whole keyboard gets messed up very badly, I cant use not a single button
tab becomes win+tab
space bar gives me selection on keyboard language
and every single letter popes up a kind of configuration window
before that I used to shut down the game, and reboot computer
but I came to a solution to only refresh explorer from task manager
still I cant figure out what is causing this mess
