Sudden reduced gui functionality

Linux beginner, not tech illiterate. Got my first Qubes rig running a few weeks ago and have been running through just very basic things to learn stuff. By far the biggest thing I did was install a Windows VM, I really haven’t dug under the Qubes hood at all. I don’t think anything had changed at all when the following started: the desktop loads and I can interact from there with the right-click menu including starting a terminal but none of the rest of the gui appears. So no menu bars, etc.

If not a known issue I missed with my searching I’d like to try getting into logs and troubleshooting just for the learning experience if anyone can point me in the right direction. Thanks for any help!

Looks like this problem:
