The problem seems to be related to not being able to receive the app installed succesfully Intent, caused by Error BroadcastReceiver components are not allowed to register to receive intents. This is on an Android 11 AOSP device.

I wonder why this issue is raised on an Android 11. This issue could happen on earlier Android OS builds (up to 5) but it has been fixed in later Android versions.

Anyway, I think nothing could be done with this as this seems to be the Android OS bug. At least, Android documentation doesn't mention this restriction, and the last mention of this issue on stackoverflow is dated by 2013.

The exception is caught in the Headwind MDM code and just logged.

Okay, I am not totally sure that error is the cause of the issue. Maybe it is just logged.

I am also seeing this Exception, does this look like an issue?

You are right, this one is something more serious. This issue will be diagnosed and fixed in further versions of Headwind MDM agent.
