HMD won't capture the display even when it connects to SteamVR

[snagar]

I don't know exactly when this started, all I know is that previously when I launched a VR game, namely No Mans Sky" on my CachyOS, it was behaving just fine from VR perspective. I did few OS updates, but I was able to always connect my ALVR client to the OS, and I always saw SteamVR horizon screen, which made me believe that VR should function correctly. Unfortunately, when I tried NMS two weeks back, the game was loading correctly, on the screen, but the HMD fail to capture the Display, worse, I was able to see the NMS window opening and then closing, crashing the game with it. I have no idea if this relates to the Window Manager, wayland or driver. All I know that the only VR game that does work, for now, is Moss 2, which is an UE4 game. The rest of the games, NMS, Metro Awakening VR do not capture the display and controllers, and they could crash, unfortunately without a log.

How can go about and troubleshoot the issue at hand ?

Thanks Saar

This issue seem not to be an ALVR issue but also WiVRn, so it might be relates to the Display interface between Wayland and the HMD, although, I can't explain why Moss II and X-Plane works fine.
