Mouse input bug, floating, sliding

I still have issues similar to the earlier mouse input bug from a few months ago. I did not play during the initial mouse input bug, but I have returned to the game, and the problem is exactly the same as what I've seen googling - my mouse is hardstuck and floats for 3-4 seconds with my character running forward / sideways. Please advise on how to fix this on my end if such a thing is even possible. Thanks a lot.
