SteamVR linux files missing, libnvidia-ml.so does not exist

Description

Two errors show up upon opening ALVR and clicking "Launch SteamVR". One says "SteamVR linux files missing, aborting startup, please re-check compatibility tools for SteamVR or verify integrity of files for SteamVR", and the other one says "Can't initialize NVML engine, error: a libloading error occurred: libnvidia-ml.so: cannot open shared object file: No such file or directory."

I'm a Debian Testing user and I also use KDE Plasma. I checked where ALVR is looking for NVML with this command: strace bin/alvr_dashboard 2>&1 | grep -E '^open(at)?\(.*\.so' ALVR looks in a lot of places but none of those places contained libnvidia-ml.so. I ran this command on my machine and after that ALVR worked: sudo ln -s /usr/lib/x86_64-linux-gnu/nvidia/current/libnvidia-ml.so /usr/lib

im having a simmular issue with the same text: "SteamVR linux files missing, aborting startup, please re-check compatibility tools for SteamVR or verify integrity of files for SteamVR." But i dont have any driver issues. Im on arch with KDE plasma and i have no idea what could be causing this issue. Please ask me for anything like logs n shit cuz i have no idea what i need to give.

I just boot up Windows now instead of trying to make ALVR work. It's the simplest way of playing VR as a Linux user.

Got the same issue, I get the following error when using the "Launch SteamVR" option in ALVR:

SteamVR Linux files missing, aborting startup, please re-check compatibility tools for SteamVR, verify integrity of files for SteamVR and make sure you're not using Flatpak Steam with non-Flatpak ALVR.

I also can't launch steamVR from Steam, it just crashes. Not sure how to collect logs for steamvr though

Btw. I'm running cachyos (arch linux) with nvidia gpu. I don't have issues running games and can also run WiVRn without any issues. I've tried to verify/fix SteamVR files but same issue

I've noticed nvml-wrapper got updated and will create PR to update it, hopefully this will fix the issue (it has mentions to looking at different library, so this interested me to check for issues)
