Hyprland crashes on startup after update (SIGABRT in CMonitor::CMonitor / onNewMonitor)

[nowardskaul-cyber]

Hi, I’m running into an instant crash right after updating Hyprland.
Before the update everything worked fine, but now Hyprland aborts immediately after logging in.

I'm using an AMD integrated GPU.
If this is due to a regression in the latest release, I hope this helps narrow it down.
Thanks in advance!
