Wierd (GTK?) Keyboard Issue

PB 6.21 on Mint 22.2 w/ Ubuntu 24.04

I recently bought a little HP mini with 32gb/1tb memory and Win-11. I never booted windows, just installed Mint.

PB was installed with no issues and has been working as expected. I was tinkering with some old Win10 PB apps when my "Q" keyboard button stopped working in the IDE. The USB keyboard on all other editor-type software works fine, just not within PB. This happened soon after I received a garbled GTK error due to a programming goof up on my part. I suspect I've somehow corrupted my GTK system.

In my ~/Apps/purebasic-621/compilers/ dir, there are:

purebasic
burebasic_gtk2
purebasic_qt

executables. Running either of the first two starts the IDE and produces the same problem. The qt one works normally and the "Q" works.

The following didn't fix:
1) Rebooting
2) sudo apt-get reinstall libxxf86vm-dev libxine2-dev unixodbc-dev libsdl1.2-dev libsdl2-dev libssl-dev libvlc-dev libgtk2.0-dev libgtk-3-dev
...then rebooting
3) sudo apt-get install libwebkit2gtk-4.1-dev
...then rebooting.

I don't fully understand the marriage between PB and GTK so I'm reluctant to dive into things without some help. Any ideas on what's wrong would be appreciated.

It is also possible that the purebasic.prefs file is damaged. Delete it (PB IDE closed) and perform the settings again.
Path /home/[user]/.purebasic

mk-soft, you got it! Thanks for the clue.

Something similar happened on my Win computer and it was a corrupted value in the shortcuts definitions.
Anyway, I copy-pasted my editor color scheme into a fresh .prefs file and all is well.
