When I create a new MAUI app, I get the following

@DevCisse make sure to install JDK 11 and make sure it is set properly -> https://docs.microsoft.com/en-us/dotnet/maui/get-started/installation#android

Thanks James. I am not sure what happened. But I had to install Xamarin Workload in VS 2019 and I created an emulator there. I then came to VS 2022 and was able to run it.
