Forked App not booting on emulated device

Hello all,
I am trying to fork this open source project and test it on VS19(Xamarin): XamFood (search it on github, I can't post links yet)
The app seems ok, and there are not errors in compilation.
When I try to boot it on my device, using Debug or Release, the App does not run, and I get no errors about it.
There are App and Appshell.xaml/xaml.cs files inside the project, so the main booting project should be already declared.
Also there are Android and IOS Projects, but I want just to test it in android.

I am using:
VS19
Pixel 9 Pie(Android 9, Api 28) as emulated device, also tried with Android 6.0 Api 23-24 Nexus S

Could anyone help me? Thanks in advance
