Hi Daniel Amorim,
While checking the issue on our end, this occurs due to the missing package reference "Xamarin.Android.Support.Design" in the Android project. Kindly add this package to your Android project and let us know whether the issue gets resolved or not.
However, this issue can be overcome without adding the package reference and this will be fixed in our upcoming 2022 Volume 1 main release.
Regards,
Sarath Kumar.
