[BUG] SteamVR Doesn't Properly Close

[Meolsei]

Describe the bug
After quitting SteamVR from the VR menu, Steam continues to show a 'Stop' button which is unresponsive and does not kill the remaining processes. The only resolution I've found is manually sending a SIGKILL to the remaining proecsses, after which Steam finally updates.

To Reproduce
Steps to reproduce the behavior:

1. On the Meta Quest 2, launch SteamVR using Steam Link
2. Quit SteamVR from the VR menu
3. Observe the Steam UI stuck on the unresponsive 'Stop' button.

Expected behavior
SteamVR should correctly shut down, and Steam's UI should return to the normal 'Play' button state.

System Information (please complete the following information):

• Steam client version (build number or date): 1777411435
• SteamVR version: 2.15.6
• Distribution (e.g. Ubuntu): CachyOS
• Steam runtime diagnostics: runtime.txt
• Steam and SteamVR logs: steam-logs.tar.gz
• Minidumps: steam-minidumps.tar.gz

Screenshots

Additional context

• Headset: Meta Quest 2 (Via Steam Link)
• Window Manager: i3 over X11
• CPU: AMD Ryzen 5 3600
• GPU: AMD Radeon RX 5500 XT (AMDGPU)
• Audio: PipeWire with WirePlumber

I've only had the issue recently, but the workaround I've resorted to is by sending a SIGKILL to the following processes:

pkill -9 vrserver
pkill -9 vrcompositor
pkill -9 vrdashboard
pkill -9 vrmonitor
pkill -9 vrwebhelper

journalctl shows zero SteamVR related output at any point.
