I am also having this issue
XF version 4.5.0.617
VS 16.5.4

but my porblem, was resolved later by upgrading the nuget packages
Xamarin.Form.Visual.Material to the same version as Xamarin.forms
and upgrading the RG popup plugin nuget to 2.0.2
and also cleaning and deleting bin/obj of the android project.

Could you attach a repro sample?. If this is not possible, you could share more information such as:

Xamarin.Forms version used, etc.

Xamarin.Forms: 4.5.0.282-pre4
Xamarin.Forms.Visual.Material 4.4.0.991640

PS:
The error occurs with Xamarin.Forms 4.4.0.991640 too.

I returned Xamarin.Forms until version 4.2, and the error continued.
After that, I installed the stable version of Visual Studio and managed to compile normally.

@mariohik What version of Visual Studio were you previously using and what version are you now using? Thanks!

This error was happening in Version 16.5.0 Preview 4.0.
I just upgraded to Version 16.5.0 Preview 5.0 and the error is no longer occurring.
