I found interesting dom0 logs:

dom0 qvc.ScreenShare+-disp6823[12773]: Traceback (most recent call last):
dom0 qvc.ScreenShare+-disp6823[12773]:   File "/usr/share/qubes-video-companion/sender/screenshare.py", line 81, in <module>
dom0 qvc.ScreenShare+-disp6823[12773]:     screenshare = ScreenShare()

dom0 qvc.ScreenShare+-disp6823[12773]: gi.repository.GLib.GError: g-io-error-quark:  Error calling StartServiceByName for org.freedesktop.Notifications: Timeout was reached (24)

BTW I’m running Qubes R4.2 (fc37 dom0) and KDE.

And commenting out Notify.Notification.new(app, msg, icon).show() fixed this for me.
