Comment (by szhorvat):

 I am not experienced with crash logs. I looked in Console and found
 something that looks like an afsctool crashlog from yesterday. I attached
 it. I couldn't find the one produced by today's crashes.

 Re RJVB's comment: I CC'd him because I thought that the MacPorts version
 of afsctool was the same as his fork (given that he is active here). The
 original afsctool from https://brkirch.wordpress.com/afsctool/ has not
 been updated in 7 years. There are several forks on GitHub, but with a
 tool that has the potential to cause data loss, I am not entirely
 comfortable trying versions from random people I do not know at all.  This
 is especially true now, as Apple has switched file systems.
