From your description, I know our issue is that ATP installation crash on Android device. We already tried to upgrade the Android system and reassign the compliance policy. But the issue still persists. Based on my researching, I find the following official article says that only Work Profile enrolled devices are supported to install Microsoft Defender ATP in Android Enterprise.

Could you check if our device is work profile enrolled?

However, if it is, please collect the following information to clarify:

1. How many Android devices are affected? Did they use the same enrollment method?
2. What are the difference between the working devices and the affected devices?
3. What are the compliance status of these affected device?
