I has a similar issue when running Ubuntu on Windows with WSL2.
What it works for me was to to follow the instructions at
https://wiki.ubuntu.com/WSL
paragraph:
Running Graphical Applications
Before I was using Xming, but gedit or any graphical visualization was not working.
Then I tried with VcXsrv and after gedit worked!

Most likely the problem is that gedit config files are owned by root.
This happens when you run sudo gedit in a terminal, that is wrong.

You can fix it by running

sudo chown -R $USER:$USER /home/$USER/.config/gedit

That will set correct ownership for these files.

Next time if you really need to run gedit with sudo (not recommended), do it this way:

sudo -H gedit

(gedit:76): Gtk-WARNING
