Issue/Bug Description:
I am using the live LTS 22.04 distribution downloaded yesterday from https://pop.system76.com/ (normal, non-nvidia). I wanted to flash an iso onto a usb drive using the Disks Utility with the option "Restore Disk Image". However, when wanting to choose an iso file and clicking on the dropdown, the entire window freezes, gets unfocused, and nothing can be done to restore it. The X button does not do anything and the parent window is locked and you have to kill the disks utility from the terminal and restart it.

Steps to reproduce (if you know):
My steps:
Booting a fresh live usb (non-nvidia), open the "Disks" application, choose an external usb drive, click three dots in the top right and choose "Restore Disk Image". Now click the dropdown saying "(None)" and both windows will freeze, forcing you to kill application from the terminal.

Expected behavior:
The dropdown simply shows an empty list and does not freeze the UI.

Other Notes:
I do not know if it also happens with a normal installation, but it happens in my fresh Live USB drive.
Also I don't know if it's an Ubuntu bug in general or PopOs specific.

Before clicking:

After clicking on the empty dropdown:

Now both windows are frozen and X does nothing.
