Bug Report

Description

When I try to run Hyprland, the application fails to start and crashes. After encountering the issue, I switched to GNOME to investigate and discovered the error related to Hyprland. During the startup of Hyprland, the application crashes, and I receive a backtrace error message as shown below in ~/.cache/hyprland/hyprlandCrashReport15875.txt:
