I have added the MAUI workload in Visual Studio 2022 v17.3.0 Preview 1.1 and I have the following set of errors after creating my project.

Errors:

I have done the maui-check and it always ends with the following:

.NET SDK - Workloads (6.0.200) Checkup... x android-aot (Microsoft.NET.Sdk.Android.Manifest-6.0.200 : 31.0.200-preview.12.2) not installed. x ios (Microsoft.NET.Sdk.iOS.Manifest-6.0.200 : 15.2.200-preview.12.4) not installed. x maccatalyst (Microsoft.NET.Sdk.MacCatalyst.Manifest-6.0.200 : 15.2.200-preview.12.4) not installed. x tvos (Microsoft.NET.Sdk.tvOS.Manifest-6.0.200 : 15.2.200-preview.12.4) not installed. x macos (Microsoft.NET.Sdk.macOS.Manifest-6.0.200 : 12.1.200-preview.12.4) not installed. x maui (Microsoft.NET.Sdk.Maui.Manifest-6.0.200 : 6.0.200-preview.12.2441) not installed. ! Managing Workload installation from the CLI is NOT recommended. Instead you should install the latest Visual Studio preview to automatically get the newest release of .NET MAUI workloads installed.
