Ok regarding my env:

$ gnome-extensions list --enabled
$ gsettings get org.gnome.shell enabled-extensions
@as []

I did not removed gnome-shell-extensions because this will break the gnome-core installed.

It crashed again this morning:

May be the problem was with libmozjs then.
I saw that a new version have been pushed:

$ dpkg -l | grep libmoz
ii  libmozjs-115-0t64:amd64                          115.10.0-1                                    amd64        SpiderMonkey JavaScript library
ii  libmozjs-115-0t64-dbgsym:amd64                   115.10.0-1                                    amd64        debug symbols for libmozjs-115-0t64

and I did an update then, so let see!
