I'm from an upgraded ubuntu 20.04 notebook that freezes less than 1 minute after login. The only time it unfrozen a bit it thrown the popup with this error. Well, at least there was the link to this bug as duplicate or something.
The solution they suggested here https://forums.developer.nvidia.com/t/ubuntu-20-04-screen-freezes-after-5-minutes-of-uptime-with-nvidia-drivers/122297 didn't work. So I think it's something in gnome--ubuntu20.04 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1868293 Title: gnome-shell crashed in meta_workspace_index: Workspace does not exist to index!
