Weird problem migrating blazor from .net 5 to .net 6.0

I migrated my blazor WASM + web Api to .Net 6.0. My web API seems OK at least in regard to compile & usage via Postman.

On the client WASM side though, after following all instruction to upgrade + updated my packages including MudBlazor, I have a 1 very weird error. It does not even point to my direct source code but compiled code in the mypage.razor.g.cs at line 1057. Here is the error: Error CS1662 Cannot convert lambda expression to intended delegate type because some of the return types in the block are not implicitly convertible to the delegate return type BlazorProducts.Client D:\BlazorSurface\OderSDT_PubV2022\Order.Client\BlazorProducts.Client\Microsoft.NET.Sdk.Razor.SourceGenerators\Microsoft.NET.Sdk.Razor.SourceGenerators.RazorSourceGenerator\Pages_OrderEdit_razor.g.cs 1057 Active

By adding the line true in my .csproj file I was able to look at the Pages_OrderEdit_razor.g.cs file and to this line #1057 below It seems to relate to the EditForm & his EditContect tag and the code is further below my compiled code. I tried some post related to that & tried several things regarding the user of tag Select versus InputSelect in my modal but it did not fixed it. Yes, I have compiled in Debug mode.

Is someone have a clue on how to resolve this error?

Whenever I have seen this delegate error, the cause was that the page was referencing a method name that didn't actually exist so double check if one needs updating.
