V4.3 qubes.Filecopy broken, Request refused everywhere

Changes:

  • Same session, no updates in between works and broken.
  • Changed policy for mouse input in timeframe via Global Settings menu (because after pressing ESC once, while the mouse allow prompt was focused, because something grabbed the keyboard and I couldn’t type, the prompt never showed up again on mouse replug or usbvm restart, I tried setting the policy off and ask again)

Troubleshooting done:

  • Policy daemon in dom0 restarted. No effect.

EDIT: Fixed it.

The XFCE notification system was stuck, therefore the prompt could not appear and the request was refused. Restarting XFCE fixed it. (The guest windows stay open even.)

Some users won’t see your edit, so it is better to make another post and mark it as the solution.
