Unresponsive context menu options for every installed entry on steam- Endeavor OS

Description:
When clicking the cogwheel (⚙️) next to any game in my Steam Library, the context menu opens, but none of the options (e.g., Add to Favorites, Properties, Add/Remove from Group) are clickable or respond in any way. The menu appears visually but is completely unresponsive.

Steps to Reproduce:

Open Steam and go to Library.

Hover over any game and click the cogwheel icon.

Attempt to click any option in the context menu.

Expected Result:
The selected option (e.g., Properties, Favorite) should execute its corresponding action.

Actual Result:
The menu shows up, but clicking any of the options has no effect. No action is triggered, and the UI remains unchanged.

OS: EndeavourOS (Arch-based)

Desktop Environment: LXQt

Display Server: X11 (checked via $XDG_SESSION_TYPE)

Steam Version: 1.0.0.82-2 (installed from pacman)
