Seems to be some problem with Xen and your wireless controller:
You can try to add pci=nomsi to the sys-net’s kernel options for a test, but I’m not sure if it’ll help. Just some random thought.
You can add this option using this command in dom0: s=$(qvm-prefs -- sys-net kernelopts) && qvm-prefs -- sys-net kernelopts "pci=nomsi $s"
