I couldn't find any existing reports of this crash. Although bug 1811024 and bug 1811025 look related.

This crash occurs at the moment the switch is switched "away" from host 1 to another host. Upon switching back to host 1, the gnome-session & gui processes have exited and the login screen is displayed. Makes it difficult to get much work done.
