Thank you for the additional information.
There might really be something more. If you have not, is it possible
to install the package "systemd-coredump".

If then a crash happens again and it gets recorded it should
be mentioned in journalctl and this command should list them:
    coredumpctl list
And a core should be stored. (But maybe just for the current boot)

There should be already a slight backtrace in journalctl
that might be helpful, but with 'coredumpctl gdb' and at the gdb
prompt with 'bt' it might reveal some more information.
Even better when sddm-dbgsym is installed, and if sufficiently RAM is 
available, libqt5qml5-dbgsym. (and some more not yet known in between ...)

There might be more pointer in:

Kind regards,
