Unity Crash with simulator, always on second start

Moin,
so my unity crashes every time I try to run the app with the Meta Simulator (V83) the second time. The first time it works, the second time it just crashes without even a crash report.

It is very annoying and makes working quite difficult.

Unity version 6000.2.2f1
Meta SDK V83

Sometimes I also get these errors. Since the Simulator changed quite a lot in V83, maybe there is an error in this current version:

Any ideas on what to check for?

  • Are you using OpenXR with the 'Meta Quest' (not 'Meta XR') feature group? The 'Boundary Visibility' feature crashes the simulator. Uncheck the feature in the Desktop tab (not the Android/Meta tab, as that does not affect the editor).
