Unfortunately your fix is not working. Even launching the SteamVR Room Setup library entry that appears after SteamVR starts gives an error dialog: "SteamVR Room Setup. An error occured while launching this game: Unknown error"
Yes! this is what fixed the room setup for me!
Nothing extracted yet.
Room setup doesn't launch. Wrong path to the vrenv.sh script
How to reproduce:
Start SteamVR 2.2.3 and try to launch room setup.
Room setup doesn't launch
How to fix:
add a folder to SteamVR install path called runtime and symlink bin into it.
