We had several fixes ready to push within a few hours after the deadline, but as much of it felt like additional functionality we ultimately decided it would be unsportsmanlike to submit - unfortunately our bug fixes were in the build as well XD.
As a team we have outlined the priorities for patching and are eager to push as soon as we can.
As for it not launching, I have an oculus quest 2 and SteamVR - I launch everything from my virtual desktop (.exe) and it kicks into SteamVR right away.
