After upgrading from Oculus XR to OpenXR plugin in a Unity project, the game gets stuck at the splash screen and fails to launch. The issue is accompanied by occlusion not working despite relevant features being enabled in settings, and 'boundaryVisibility' spamming null errors in LogCat on boot. Disabling boundary visibility stops the error logs but does not resolve the launch issue. The problem persists even after re-importing, clean building, and creating a new manifest.
