Waybar Crashes on Suspend

[portalbyte]

Currently on Arch Linux. When I suspend both monitors go off and my screen locks. When I turn it back on, Waybar has crashed. The console often displays different messages, but they all end the same - that my config has an error in it. Yet my config is fine. What is happening?

This example has a HEADLESS-1 error, but this doesn't always show up.

The error message is referring to json content from hyprland IPC, not json in the config.

I think this might have been fixed by #3389. Any chance you can try git version of Waybar?

Just tried the -git version, no issues! Appears to have been fixed.
