GUI Disappeared, Can't Get It Back

[W4phle]

Linux Mint 21.1: In the GUI prompt, clicked the NO option to auto-enable bluetooth, the GUI disappeared and now won't return.

When I click the applet to launch it in the System Settings it pops up for a millisecond and again disappears.

Can't get it to show, want to change to YES to auto-enable bluetooth.

Tried purging and reinstalling; no change. Restarted 4 times; no change.

Now I'm sad. :o(
