Mobile login successful, but the app is unusable and crashes frequently

[hao031410]

Phone model: Xiaomi 14
OS version: 3.0.5.0.WNCCXNM
happy version: 1.5.0

Issue as follows

1. The app crashes when opening the camera to scan a QR code without prompting for permission; after manually granting camera permission, scanning works, but it cannot connect to the PC and the home screen stays black with a spinning circle.
   

2. Frequent crashes—tapping anywhere inside the app randomly triggers a crash with no clear pattern.

3. The system crash log is below; the issue might be camera-related. The stack trace is as follows
