1 day ago suddenly i encountered the same issue, it took me more than a day to figure out the problem,finally clonig the repository and taking a look at the samples provided i noticed this package reference inside the .csproj file, adding it to my project cleared the annoying errors, i hope this helps the other guys struggling the same issue
<ItemGroup Condition="'$(TargetFramework)' == 'net8.0-android'">
