@shuvashish76 have you enabled battery restrictions/some other types of background restrictions on your device when this crash occurred? 🤔

PS: I found this, but just wanted to confirm.

[shuvashish76]

Everything set to default. I'm not sure.

This can be solved, at least in my case, by switching the app's battery settings to "Unrestricted" (or whatever it's called in the OS and language you use). Used to be "Optimized".
