** Description changed:
I added a new keyboard layout ("A user-defined custom Layout") on Ubuntu
25.10 with most things default. Then when I pressed the view layout
button in settings and pressed like 2 "keys" with my mouse the system
became unresponsive, a few seconds later Gnome Shell crashed and the
login screen appeared. When I tried to log in and put my password, there
was some error and I couldn't enter the password again to retry. I
switched to a TTY but couldn't log in because some error was getting
printed every second. Finally I rebooted and nothing changed, I still
had the issue. After booting into recovery mode and moving the config,
local, and cache folders along with a few other things there, I rebooted
and everything went back to normal (only my user preferences got reset).
I've attached the log (the problems start at about 13:35 I think). From
what I understand this is a Gnome Shell bug (or at least partially) but
I could be wrong though.
I'm also attaching an image of the Settings app where that happened. I
want to note that this is not a user-created problem as it was an option
in the official Settings app that didn't even require authentication.
Adding a keyboard layout layout should not lock anyone out of their
computer.
Also adding a link to my Ask Ubuntu question as there is a fair bit more
information. https://askubuntu.com/q/1564645/2439079

+ P.S. The logs are very telling. A double free (or corruption) happened,
+ Gnome Shell got terminated for that double free and... I honestly don't
+ know. If you can, please read the logs.
