(Context: this has been going on for months without a fix)
Every time that I open the game [Quest 2, Virtual Desktop], it fully boots as normal, but none of the textures that should be loaded seem to load. I can't really explain it too well so I've provided images of the situation.
Attempts to fix this have not bore fruit, ranging from verifying files, restarting PC, reinstalling game, manually deleting all traces of the game off the PC using REVO Uninstaller, ensured SteamVR is up to date, made sure that Quest 2 headset is up to date.
