Gnome-shell crashes with "meta_monitor_manager_get_logical_monitor_from_number: assertion '(unsigned int) number < g_list_length (manager->logical_monitors)' failed"

Affected version

Running up-to-date Arch.

mutter 46.0-1

gnome-shell 1:46.0-1

Bug summary

Seems like crash happens when I disconnect my dock from my laptop. This makes 2 external displays disappear, and makes gnome-shell crash.

Similar to #2846 (closed) , but no tiling extension installed.

Never had it in previous versions, only since update to 46.

And this seems to cause gnome-shell to crash:
