There's not a whole lot of info in this backtrace for us to really know
what's going on but can you try with 13.18.4?  There have been recent crash
fixes that may help.

If 13.18.4 doesn't help, recompiling with debugging turned on, re-creating
the issue, then following the wiki instructions to get a backtrace will
help us figure out what's up.
