$Count is not working with .NET Core and ODataQueryOptions

I am using Odata with .NET 5.0. Odata version is : (Microsoft.AspNetCore.OData\8.0.1)

$Count is not working in my each request.

http://localhost:33451/odata/Users?$count=true
http://localhost:33451/odata/Users?$skip=20&$top=10&$count=true
http://localhost:33451/odata/Users?$filter=Salary gt 20000 and Salary le 50000&$count=true
http://localhost:33451/odata/Users?$skip=20&$top=10&$filter=Salary gt 20000 and Salary le 50000&$count=true

I am using ODataQueryOptions without EnableQuery.

I also gone through to remove "ApiController" and [Route("[controller]")] but it was not working.

Start by reproducing the request against UsersController.Get in the attached sample and review the OData setup in Startup.ConfigureServices. Trace how ODataQueryOptions are applied for filter, skip, and top, and compare that path with the requested count behavior. Done means the response includes the expected count for the shown requests without breaking the other query options.
