Xamarin-android: Xamarin.Android gone AOT and LLVM checkboxes.

I suddenly found that I can not turn on AOT in the settings.
How could this happen?

I have the same issue. After the newest update, this option disappeared.

Thanks for the report! It looks like something unexpected might have happened with the edition of Visual Studio being launched. Your version information shows that the running Visual Studio instance was Visual Studio Community. The AOT Compilation and Use LLVM Optimizing Compiler settings are only available in the project property pages in Visual Studio Enterprise.

As a first check, you could try launching Visual Studio Enterprise from a cmd.exe command prompt or a Windows-R run prompt. For the default installation path, use the following location:

"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\devenv.exe"

If you ensure that the running Visual Studio instance is Visual Studio Enterprise by launching it that way, do you see the settings again? Thanks in advance!
