Then, I receive a critical error message - which originates from qubes Manager.
I was going to paste the text into nano and screenshot for debug here, but I get code execution warning (I guess because it references python functions).
Still, strange ‘critical error’, given there was no apparent malfunction.
This is the same error.
Did this appear after a particular action?
As above, for me, there was no apparent action, other than opening the dispVM (which opened & ran without any other issues), which I could think initiated this.
