Since you tried the AppImage and reproduced with that as well, could you
consider filing a bug report upstream directly at
https://gitlab.com/inkscape/inbox ?


Also, I'm uploading now 1.0-5 to backports, if you could see whether
that also triggers this crash it would be useful (1.0-2 disable a bunch
of asserts that might or might not be relevant).

Likewise, if you can get a stacktrace it usually helps nailing down where
the bug is.
