If you open the projects screen, and change a user, and then go back to the current project to select it, Resolve crashes on the attempt to select it. but opens fine when you go right in and select the project without changing the users.
I just tried to do the same thing and it happened. Not sure what I even did to trigger it but I simply started a blank project under my own user, logged out and back in as guest, opened the shared project sidebar and it crashed when I clicked around on some projects under my account. I didn't even try to open or import anything.
