Hi I have the same probleme here, it crashes constantly. Tried everything suggested on this thread but so far I had no luck with it. Yesterday I thought clearing the preference solved it, because after that it worked but today it's crashing again. Also the shortcut for the bugreport seems not to work, like other people experienced as well.
Fortunatley my old R20 licence is still active, so I'm switching back to that for now because I can't work like that, but I really hope this problem gets solved soon, I'll be checking this thread for updates 😄
Operating System and version: Windows 10 2004

What were you doing at time of crash: Happens randomly, for example when switching between view ports (or just moving in one viewport), unhiding all selected itmes or just while adding a loopcut or using the slide tool.
