Try to run the nextcloud client or the protonmail-bridge in a VM in 4.1. It closes all the windows open in the VM, and there’s no way to open any new windows, even using
$ qvm-run vm xterm
from dom0.
The VM remains running, however. I can kill the VM and restart it and open a terminal, but again, when running either of those two programs, it will crash heavily.
Here are logs from that vm (I called it “e”):

Any hints on making this work?
