Hyprland modules not loading properly, IPC unable to connect

[xiyori]

Sometimes all Hyprland modules fail to load. Happens both on startup and after hypridle. The modules are visible and respond to click and scroll actions, however, they do not update, for example, workspaces module always shows one workspace and language module shows empty string.

System/Version info

Waybar v0.11.0

Hyprland, built from branch  at commit 0f594732b063a90d44df8c5d402d658f27471dfe  (props: bump version to 0.43.0).
Date: Sun Sep 8 16:48:21 2024
Tag: v0.43.0, commits: 5196

Relaunching waybar always fixes the issue, but it happens again after some time. I tried a fix from #3230 ln -s $XDG_RUNTIME_DIR/hypr /tmp/hypr and it didn't help much.
