Describe the bug
The first time you run multipass.gui in your system it behaves as if you set it to close all running instances on exiting the GUI. When looking at the settings this is not the set option. If the option is "re-set" to "ask", the GUI behaves as normal.

To Reproduce
From a clean system:

1. Build multipass
2. Run multipass.gui
3. Close the GUI with a running instance
4. The GUI will not ask to close
5. The settings option is set to "ask"

Expected behavior
It should behave as the default settings option indicates it should: to ask to close or keep the instances running when the GUI is closed.

Additional info

• OS: Windows 11 Pro
• CPU architecture or model: amd64
