awesome! thanks

[mrdoob]

@cabanier The editor no longer loads on the Quest Pro after this PR.

[cabanier]

o woah! The crash corgi!
Can you hit the oculus button 5 times and file a bugreport?
Also if you have adb can you do adb logcat > out.txt, reproduce the crash and send me the log file?

[mrdoob]

I don't have adb unfortunately...

Are you able to reproduce on your Quest Pro?

[cabanier]

I'm on PTO this week. I'll forward to my team

[mrdoob]

I've filled a bug report. It crashes on Quest 3 too.

[cabanier]

how do you reproduce? Just open the URL above and go immersive?

We got your report.

[mrdoob]

Just trying to open the URL is enough. The browser will try a few times and then corgi appears.

I have attached an adb log if this still is valid from the corgi circular loop.

I found the issue on our side. You're calling offerSession very soon after page load at which point we didn't initialize WebXR yet.
I will fix this for the next browser version.

[mrdoob]

Excellent. What browser version will that be?

Either 32.0 or 32.1
