It seems to be related to doze mode. Some device may require the `android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS` permission. Are you using another plugin in your implemented TaskHandler? Or are you using the network?

This issue seems to be related to [Doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby) on the Android platform. When using the service for extended periods of time, it is recommended to turn off battery optimization...

It seems to be fine on real devices with Android 9.0 and lower. Can I know the development environment and the version of the device you tested? I will continue...

Did you request and grant "android.permission.SYSTEM_ALERT_WINDOW" permission? The above permission is required to use the launchApp function in apps on Android 10 (API level 29) and higher.
