AeroSpace Runtime error after changing displays

For some time now, I've consistently gotten the error shown below when changing from using an external display to the built-in one or vice versa. To restart aerospace after crashing, I have to force-quit and the re-open it.

Steps to reproduce:

Aerospace running normally when using on an external display (Macbook in clamshell mode)
Lock computer/Turn off external display
Open laptop and use the built-in display

This sounds like same error I've been seeing for a little while, certainly more prominently since updating aerospace last week. Runtime error collapsed.
