Why am I getting "The current .NET SDK does not support targeting .NET 9.0. " when I have .Net 9 Preview Installed?

I would like to try the new .NET MAUI Blazor Hybrid and Web App template. I installed the latest .NET 9 Preview but I am getting the below errors when the template is immediately opened / built.

I have the latest VS installed. 17.11.3

I have .Net 9 Preview 7 Installed on my machine. Why am I getting the errors?
