.NET MAUI, Android emulator is not ready to be used

Question

I have also tried cleaning project, but it did not workI have installed x64 android emulator with API 21 on AMD CPU to get higher performance when I try to start debugging on it, I get 'There were deployment errors' and in the output window:

Waiting for emulator to be ready...
Emulator is not ready to be used.

I have followed this answer with no luck

I have tried to deploy manually to see if the issue is from the emulator or Visual Studio

1. I have published the app to an apk
2. and using the adb tool found in 'C:\Program Files (x86)\Android\android-sdk\platform-tools' I installed the apk using the command adb install <apk_file_path>.it installed the apk successfully and I can launch the app
3. then I tried to start the app using adb tool so I ran the command adb shell am start -n com.package.name/.MainActivity I got:

Error type 3 Error: Activity class {com.package.name/com.package.name.MainActivity} does not exist. Failed to launch android application

1. so I added Name property on the Activity attribute on the MainActivity class and I have set it to "com.package.name.MainActivity", after adding this property the app worked properly using adb but still same issue in Visual Studio I have also tried cleaning project, but it did not work
