Whenever I deploy my application to my Android phone, it produces the error called
""GetVersionTask" failed unexpectedly." When I run it using Windows Machine, it runs completely normal. What could be the solution to this?

Do you debug your application with VS?

Or do you release application, then generate .aab or .apk file, install .aab or .apk file in you android phone?

it produces the error called ""GetVersionTask" failed unexpectedly."

Where did you get this error? From VS output error or other places.

You can try to deploy your application to android emulator, is that working?

Yes, I do debug my application with Visual Studio. Slight correction, "VerifyVersionTask" is what's appearing as an error when I debug it and try to release it on my Android phone.

Did you try to debug it in your Android emulator? If you can debug it in your android emulator, this issue is related to your Android phone. If not, please copy your .csproj file here. I will try to reproduce this issue. Please share your VS version as well.

It doesn't let me upload the csproj file here. But here's the whole code.

	The default runtime is maccatalyst-x64, except in Release config, in which case the default is maccatalyst-x64;maccatalyst-arm64.

	When specifying both architectures, use the plural <RuntimeIdentifiers> instead of the singular <RuntimeIdentifier>.

Please change the net8.0-android34 to the net8.0-android in <TargetFrameworks>, if you use the latest .net version, android target-framework version will be set android 34 automatically.
