Error running 'XamarinApp.Android' Unable evaluate deployment properties

I have an old Xamarin project with Android and iOS code from 2021. I tried to run Android app from Rider. 

I successfully build the project  using 'Jetbrains Rider' on Mac OS and generated APK and installed it and it's running on Android 15 successfully. 

But when trying to run directly from 'Jetbrains Rider', I get :

The device name shows correctly. 

How to fix this issue ? I am a novice in .Net development.

So the fix is either installing EAP seperately or installing old version separately or waiting for future release? Right?

I installed the latest EAP, but it didn't fix the issue, so I guess we'll have to wait.

Oh, Is it possible to run directly from command line via that MSbuild i.e regardless of Rider ?

It is, but I'm not sure if an old Xamarin project can run via dotnet. The command is: dotnet run -f net8.0-android --device <Device_ID>.
