How to debug emacs crashes on WSL2

Question

I installed Emacs using the instructions on this site. It was working fine for a while, but recently I have started experiencing frequent crashes. E.g. every 20 minutes, Emacs shuts down without warning and without saving anything. Sometimes, I get output printed in my terminal window, e.g.,

When compiled with GTK, Emacs cannot recover from X disconnects.
This is a GTK bug: https://gitlab.gnome.org/GNOME/gtk/issues/221
For details, see etc/PROBLEMS.

I am not 100% sure that the error message is correctly diagnosing the problem. But if we assume that it is a correct diagnosis, how would I re-install Emacs so that it can recover from X disconnects? Alternatively, how can I stop X from disconnecting?

Answer 1

Since I did not find a solution to the specific issue I decided to stop using applications which require an X server with WSL2. I have had a good experience with Emacs installed via Chocolatey - https://community.chocolatey.org/packages/Emacs . I have also had good experiences with VS Code which seems to talk to WSL2 just as well as it talks to remote machines.
