Runtime error after changing displays

[nikitabobko]

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:

1. Aerospace running normally when using on an external display (Macbook in clamshell mode)
2. Lock computer/Turn off external display
3. 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.

+1 same errors for the last week or so. Laptop falls asleep and when coming back, this console error message is highlighted and have to force quit the app and restart for it to work:
