Hi Will, I suspect this is same as <https://launchpad.net/bugs/1933022>.
Can you please run this terminal command: gsettings get org.gnome.desktop.input-sources show-all-sourcesand let us know what it outputs. If the value is "true", can you change it to "false" via this command:
gsettings reset org.gnome.desktop.input-sources show-all-sources and let us know if the crash still happens. -- Rgds, Gunnar Hjalmarsson
