Crash when detaching monitors

[HarHarLinks]

My laptop is connected to 2 external DP-daisychained displays through a single USB-C connection. The directly connected monitor is the P27h-10.

My config is in 2 parts: one for the internal laptop display ("output": "eDP-1") and one for everything else ("output": "!eDP-1").

Sometimes, as I (dis)connect the USB-C, waybar crashes. I managed to capture the following log using waybar -l debug &> /tmp/waybar.log.

Relatedly, it crashes about as frequently (or infrequently, but it keeps happening now and then) when closing the laptop to suspend it.
