I finally found a workaround that works for me. I posted it in a reply on Reddit; will repost here in case it might help someone.

Basically, what I had to do is make a new Windows profile. It's an administrator profile, and all I did was switch over to it, launch the Oculus desktop software, then choose a library location, which I kept at default. Installed Minecraft in Oculus, Installed Minecraft in Oculus store... It works.

So for anyone who's already tried the registry fixes, etc. try launching the game with a different profile.

Now, I did run into a different bug that was preventing me from choosing the library location when launching the Oculus software. A registry key was missing: HKEYCURRENTUSER\Software\Oculus VR, LLC\Oculus\Libraries.

So bottom line, something is wrong with my Windows profile which I can probably fix by reinstalling Windows. But that would take me a very long time and I have too much to lose, so making a new profile was the next best thing. And after getting the game working, I was able to switch back to my own profile and it still works.

Yes, I experience this leak when using Steam VR openxr and a Quest 2 headset.

@Evan, the memory leak occurs when launching the game via desktop shortcut and Steam VR. I tried it with the link cable and Air link and it crashed each time with about 27GB RAM usage.

It sounds like you were able to launch the game normally through the Oculus library? Maybe that's how you avoided the memory problem. I have yet to make that happen; launching through the library while using the Oculus manifest results in the game running on the desktop only. Launching through the openxr shortcut and Steam is the only way I can get the game to run but then it shuts down after maxing out my RAM.

@Gerod, you need to calm down and stop taking your frustrations out on the wrong people. If the game is working for some users, there's nothing wrong with them saying so.

And the issue is that Bedrock isn't working for multiple headsets, not just mixed reality and everyone's experiences are not the same.

Still broken.

I had high hopes, but the beta still does not work for me. Rift S. The game no longer shuts down, but it launches on the desktop with a black screen.

I'm so tired.

The Oculus launcher for Minecraft has a new update. Still crashes for me, but perhaps it'll help someone else.

To everyone saying it's been 3 months, try 7. I've been waiting for a solution since last summer, right after I bought my headset. That's around the time this bug started affecting Rift S headsets. Now, it's widespread and I'm hoping that Mojang will finally take it seriously since it's getting more attention.

@Ben, I did see a comment in the Oculus store where someone fixed their game by enabling Unknown Sources. That is what made his UWP icon appear.

Unfortunately, this did not help me since I already have it enabled. I even tried adding the UWP shortcut to the library myself.

Hi. As for myself, I can confirm that I'm using the Windows 10 version of Minecraft installed through the Windows Store. When I first encountered this crash, the game was already installed before I tried it in VR. I've also tried uninstalling completely, then letting the Oculus launcher download the game.

Everyone seems to have slightly different issues. But the common symptoms are: The game launches in VR, and after checking for updates, it either shuts down abruptly or switches to 2D/Desktop. This happens whether launching the game through Oculus desktop or through VR in the headset.

On my system, the game switches to 2D mode if my registry points to the mixed reality manifest, but shuts down abruptly when it points to the Oculus manifest. I had a wmr headset previously; now using a Rift S.

For everyone who got it working by editing the registry, are you using a Rift S?

Unfortunately, VR customers are often overlooked because we make up such a small percentage of the gaming community. They honestly don't care about us.

But my default library is on the D drive. That's where all of my games are (except Minecraft.) I can't delete that library, I assume it would affect my installations. But I'll try temporarily making C the default.

ETA: Didn't work. I suspect your fix only helps the new bug caused by the most recent update. I haven't been able to launch the game in 6 months, way before this new update.

I only needed to add the new library: C:\Program Files\Oculus\Software. When I moved Minecraft to the new location, it automatically added the additional folders. Then I deleted the old location. Game still exits immediately after Checking for Updates. 😞

I'm going to try uninstall/reinstall again.

@Curtis, I just checked and Oculus has the launcher installed in C:\Oculus Apps\Software\mojang-ab-minecraft-oculus-rift\.

If I'm understanding correctly, I just need to move the installation to C:\Program Files\Oculus\Software since I've already edited the registry...

I'm getting an error, 'graphics device invalid' when trying the demo. The manifest seems to be correct, though. I'm at a loss.

Uninstalling SteamVR didn't work for me. Game launches in VR and I see 'Checking for Updates' then it immediately kicks me back to the desktop.

I had a WMR headset prior to the Rift S. I wonder if that's related to my problem. So I checked the registry, it still showed C:\WINDOWS\system32\MixedRealityRuntime.json as the default. Changed it to the Oculus runtime, but that version still won't launch. (Oculus is installed to the default folder, though my games are not.)

And there's no Openvr folder in my Minecraft folder, so no logs.

The majority of my games are in Steam, so I'm nervous about messing them up if I uninstall Steam VR. So maybe I'll try Daws' idea of editing the registry, but the OpenXR version sounds a bit more problematic than I thought. Idk.

I wonder is it safe to reinstall SteamVR afterwards. Will the game continue launching properly? Guess there's only one way to find out...

"Maybe try another clean install of Minecraft with reboot. Install Minecraft from the Windows Store and don't install the Oculus Minecraft thing.

Also maybe check that all your Windows and GFX drivers are up to date."

I did all of that first to no avail. Oh, well. Thanks for your help, anyway. I'm sure it will help others who've been wanting to play again.

I right-clicked the desktop, chose New>Shortcut, then entered minecraft://mode/?OpenXR=true. It created a shortcut to the url on my desktop. Does that sound right? Then I put on my headset, launch the game using the new shortcut, but it still opens on desktop instead of the headset. I have a Rift S.

Thanks for the heads up about the bugs. I'm willing to deal with the bugginess as long as I can play in VR.
