Culture is not supported on .NET 7

[Boot Dat]

Was working with no errors on .Net6 but after I moved to .Net 7, I get the error when I'm using the datetime picker.

i had this in program.cs :

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("en-GH");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("en-GH");

yet i get the error:

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Culture is not supported. (Parameter 'culture')
      4096 (0x1000) is an invalid culture identifier.
