The Oculus browser intermittently crashes when launching a WebXR Progressive Web App (PWA) built and packaged using Bubblewrap, resulting in an infinite loading screen that requires a headset reboot to recover. The issue is not consistently reproducible, with the app opening successfully most of the time but occasionally failing to launch. Crash events related to the Oculus browser have been captured via ADB logging during failure states, indicating a potential problem with the browser's handling of WebXR PWAs.
