I just noticed that the crash leaves a $HOME/core file:
$ file core
core: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from
'/usr/bin/Xwayland :0 -rootless -terminate -core -listen 4 -listen 5
-displayfd', real uid: 1000, effective uid: 1000, real gid: 1000, effective
gid: 1000, execfn: '/usr/bin/Xwayland', platform: 'x86_64'
Could this be helpful?
