I can't see any information to lead us to possible causes of the crash. 
I'd assume that your system generated a coredump.  If you install
knot-resolver-dbg, you can decode it by `coredumpctl info` and related
commands.  Or even extract it and send it to me (privately), but
backtrace might suffice and it's perhaps even easier for you.
