I was not getting a crash in an earlier version of Inkscape 1.1-alpha (17bc9184, 2021-03-28, custom), but it spawned many of the folowwing warnings which might point towards the issue:

(org.inkscape.Inkscape:8392): Gtk-CRITICAL **: 17:10:53.527: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed

(Unfortunately I did not record library versions, so can't say if it's a gtk issue or not)
