sounds like a kernel panic with the way you described finder after force quitting/relaunching
nothing serious, the macbook just received and attempted a "task" or "job" too big the it was not able to handle or the correlating interprocess communication with your app EDD, icloud drive and finder said yeah, idk what you want but ok ill try and got stuck on the endless possible way to make it work but is not meant to work and so things just broke lol
you should be ok with force restarting the macbook
reset nvram if happens again

if continues, find another way of doing whatever it is youre doing or reinstall os
