Android: Cannot deploy & debug on physical device (Android 12) with VS4Mac

Description

I am not able to debug any Android App on device with .NET MAUI (latest workload 7.0.92);

Something is getting deployed to the device, but never starts. Starting manually results in an immediate crash. The deployment task hangs like forever at:

Target _Upload:
    Using cached value from RegisterTaskObject
    Found device: N0AA003638K50600016

Every now and then it gets past that point, then I see a bunch of these errors:

Deploying a Xamarin.Forms app works without any problems! Deploying to the default Pixel 5 Android API 33 emulator works as well.

Steps to Reproduce

Create a new .NET MAUI App Hit the Debug button

Expected outcome: App gets deployed and debugging starts Actual outcome: Something gets deployed, but most of the time the process gets stuck. If it gets past that step, the above mentioned error is written multiple times in the output window.

We are seeing a few issues with hanging deployments on certain android devices. We are currently not sure what causes this problem. It seems to be related to the OS that is installed on the device. Switching to Wireless Debugging or enabling EmbedAssembliesIntoApk are the only work around at this time. Wireless Debugging would probably provide a better experience.

I am working on some better error handling. The idea is to detect when this occurs and use a fallback (but slower method) of fast deployment. But issue a warning that Wireless Debugging might be better for this device.

@dellis1972 I will try when I get the chance.
