Finder 11.1 was suddenly not reacting on macOS BigSur 11.2.
Together with it Numbers and Preview Apps also did not work and had to be stopped eventually by force.
I have also noticed that only one account (out of four) had this issue. Other 3 did work just fine and had none of described issues.
After spending a couple of hours on this problem and trying to implement couple of solutions: https://blog.pcrisk.com/mac/13288-finder-not-working-on-mac I have discovered the solution which has worked for me. Therefore I want to share it here.
I simply had logged off with my Apple ID account from macOS user account I use by using System preferences app.
As soon as I have had completed this procedure Finder app started to work properly.
Soon after that I have again logged in at my Apple ID account and everything just kept working fine.
