SUMMARY This is possibly a Discord issue or Xwayland issue, but this issue doesn't exist on Gnome Wayland. Trying to start Discord either native or Flatpak results in Discord not starting and above message appearing.
This might be similar to 452243.
If Xwayland crashes it's an xwayland bug. Even if we're sending it wrong information it shouldn't crash. Can you try and get a backtrace (coredumpctl?) and report there.

Normally I would be able to do so, but even with debuginfod there is almost nothing in the backtraces.
Just had the same issue with vlc, so this is not a discord issue. To clarify, vlc does start and can play an audio file, only the main window doesn't appear. Backtrace looks like this: #0 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=6, no_tid=no_tid@entry=0) at pthread_kill.c:44 #1 0x00007f34e5a603d3 in __pthread_kill_internal (signo=6, threadid=<optimized out>) at pthread_kill.c:78 #2 0x00007f34e5a10838 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #3 0x00007f34e59fa535 in __GI_abort () at abort.c:79 #4 0x00005594e8e37981 in ??
