Blazor Anchor Link Navigation Routing Issue with Multiple Parameter and hash id

Question

I was trying to create Anchor Link or Bookmark for some contents. My issue is on click bookmark href link it scroll and take me to content right but my problem is it throws Unhandled Error throws on Blazor Page. Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Cannot parse the value '7900#headerC' as type 'System.Int32' for 'Wid'. System.InvalidOperationException: Cannot parse the value '7900#headerC' as type 'System.Int32' for 'Wid'. . This error happens as its takes my # id appended to parameter as single one but which two seperate ones.

My Reference doesn't contain parameters passed but I have parameters in my page along with hash id.
