Mint 21 'cinnamon-settin' core dump when try create 'connect to hidden network'

[pidle]

 * Graphics hardware - NVIDIA G92GL [Quadro FX 3700] driver: nouveau v: kernel
 * 64 bit

Issue
Not able to create a connection to a hidden network other than on the primary wifi device because a core dump is generated.

I have both a pci wifi and a usb dongle. When I select the dongle as the device for the connection, two seconds later the UI panes disappear and a core dump is reported in the system log. If the pci wifi card is chosen as the device I can successfully create a 'hidden connection' (but cannot use as my 'hidden SSID' is 5ghz and the pci wifi is only a 'g' radio).

Steps to reproduce
See 'additional information' for the environment.

Need a PC with 2 or more wifi devices. I have a generic pci g radio and usb dongle (linksys wusb600n).
From Network Manager 'network settings', select wifi and then 'connect hidden network'
Chose the non-default device.
1 or 2 seconds later the UI closes and a core dump is recorded.

Expected behaviour
Allow you to continue to select the parameters for a Hidden Connection on any wifi installed wifi device.

Other information

• This core dump problem exists in the M21 beta (k5.15.0-39, cinn 5.4.2, vanessa) thru M21.3 (k5.15.0-100, cinn 6.0.4, vanessa).

• This problem does NOT exist in M19.3 (k5.15.0-34, cinn 5.4.2) OR in M20.3 (k5.4.0-91, una).

• The UI for 'Connect to hidden network' is visually different in M19.3. The UI appears to be the same in M20.3 thru M21.3.

• This problem DOES NOT appear to be specifically related to a usb dongle (mine is a linksys wusb600n).

• For whatever reason, the M21 beta release, in the 'Con hid net' UI, shows my usb dongle to be the default device to set up.

• The other releases I have tried show the generic pci wifi card as default.

• Using the M21 beta, the fault/ core dump happens when I select the pci wifi as the device to 'Con hid net'.

--So the fault/ core dump appears to occur when a non-default wifi device is selected in 'Con hid net'.

-- Which implies the need for 2 or more wifi devices installed in a machine for the fault to occur.

Attached is the proper dump file with relevant info.
