Boxes does not work properly with ubuntu desktop non admin user

[hmvago]

I can't finish the installation of a guest OS (Ubuntu 24.04.3 LTS) under boxes. I'm running Boxes as a Desktop User Account type under Ubuntu 24.04.3 LTS. While installing the Boxes windows closes by no reason.
The same thing has no problems if I run Boxes as a Desktop Admin Account Type.

I'm using Boxes 45.0-fe0ca77 installed from the Ubuntu Snap Package
