I believe there may be some other error logs before, could you provide it to help resolve the issue?

Thanks for feedback.

• app crashes on my test device, ZTE Blade, Android 11, API 30

• app runs correctly on Simulator, Pixel 9 API 36. That's cool

• app crashes on my test device, ZTE Blade, Android 11, API 30

For me it's the exact opposite. Runs correctly on my Oneplus N30 5G (API 30), but my emulator (API 30) crashes with the following output:
