The cli functionality is all there and working, it is just the UI. Sometimes I can guess my way around and launch a VM, but for any guest I am using the screen does not refresh.[[BR]] [[BR]] Attached are the VBoxBugReport and a screenshot of the partial UI.[[BR]][[BR]] I would love to take the time to troubleshoot more, but I just don't have it as this is my main system and I need it up and running for work. I am wiping it and reinstalling Ubuntu 20.04 with Cinnamon 4.4 in which Virtualbox works just fine." defect new GUI VirtualBox 6.1.14 Cinnamon 4.6, Linux Mint 20 all Linux
