Odata not working with Edm model loaded from file

Assemblies affected
ASP.NET Core OData 8.x

Describe the bug
When trying to read a edm model from a file, Odata stops working.

Reproduce steps
Create two entity:

 public class User
    {
        public string Id { get; set; }
        public string Name { get; set; }
    }

    public class Book
    {
        public string Id { get; set; }
        public User Author { get; set; }
    }

Create two controllers:

public class BooksController : ODataController
   {
       [EnableQuery]
       public IActionResult Get()
       {
           
           return Ok(new[] { new Book { Id = "1" }, new Book { Id = "2" } });
       }

       [EnableQuery]
       public IActionResult Get(string key)
       {
           return Ok(new Book { Id = key });
       }
   }

and

public class UsersController : ODataController
   {
       [EnableQuery]
       public IActionResult Get()
       {

           return Ok(new[] { new User { Id = "1" }, new User { Id = "2" } });
       }

       [EnableQuery]
       public IActionResult Get(string key)
       {
           return Ok(new User { Id = key });
       }
   }

Startup class:

public class Startup
   {
       public Startup(IConfiguration configuration, IWebHostEnvironment env)
       {
           Configuration = configuration;
           this.Env = env;
       }
     
       public IConfiguration Configuration { get; }
       public IWebHostEnvironment Env { get; }

       public void ConfigureServices(IServiceCollection services)
       {
           services.AddCors();

           services
               .AddMvc(o =>
               {
                   o.EnableEndpointRouting = false;
               })
               .AddJsonOptions(options =>
               {
                   options.JsonSerializerOptions.AllowTrailingCommas = true;
                   options.JsonSerializerOptions.IgnoreNullValues = true;
                   options.JsonSerializerOptions.NumberHandling = JsonNumberHandling.AllowReadingFromString;
               });

           services.AddControllers()
               .AddApplicationPart(Assembly.GetExecutingAssembly())
               .AddOData((setupAction, serviceProvider) =>
               {
                   setupAction.EnableAttributeRouting = true;
                   setupAction.RouteOptions.EnableUnqualifiedOperationCall = true;
                   setupAction.RouteOptions.EnableQualifiedOperationCall = true;
                   setupAction.RouteOptions.EnableKeyAsSegment = true;
                   setupAction.RouteOptions.EnableKeyInParenthesis = true;
                   setupAction.QuerySettings.EnableCount = true;
                   setupAction.QuerySettings.EnableSelect = true;
                   setupAction.QuerySettings.EnableExpand = true;
                   setupAction.QuerySettings.EnableSkipToken = true;
                   setupAction.QuerySettings.EnableFilter = true;
                   setupAction.QuerySettings.EnableOrderBy = true;
                   setupAction.QuerySettings.MaxTop = null;
                   setupAction.AddRouteComponents("api", GetEdmModel(), serviceCollection =>
                   {
                   });
               });

           services.AddHealthChecks();

           services.AddRouting();
       }

       public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILogger<Startup> logger)
       {
           app.UseCors(x => x
               .AllowAnyOrigin()
               .AllowAnyMethod()
               .AllowAnyHeader());

           if (env.IsDevelopment())
           {
               app.UseDeveloperExceptionPage();
           }

           app.UseRouting();
           app.UseMvc();
           app.UseEndpoints(endpoints =>
           {
               endpoints.MapControllers();
           });

           app.UseHttpsRedirection();

           app.UseHealthChecks("/health");
       }

       private IEdmModel GetEdmModel()
       {
           ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
           builder.Namespace = "MyNamespace";
           builder.EntitySet<User>("Users");
           builder.EntitySet<Book>("Books");

           var edmModel = builder.GetEdmModel();
           SaveEdmModel(edmModel);

           return edmModel;
       }

       private void SaveEdmModel(IEdmModel model)
       {
           using (var writer = XmlWriter.Create("edmModel.xml"))
           {
               model.TryWriteSchema(writer, out var errors);
           }
       }
   }

After that, both entities must be registered and we can run the project and request books or a book by key.

Everything is working.
When we first started the project, we saved the schema to a file.
Let's change the GetEdmModel() method to read from a file

private IEdmModel GetEdmModel()
        {
            using (var reader = XmlReader.Create("edmModel.xml"))
            {
                var readers = new[] { reader };
                SchemaReader.TryParse(readers, out var edmModel, out var errors);

                return edmModel;
            }
        }

Let's restart the project and try to execute the same queries.

We can see that odata.context is missing.

The same situation

And if we trying to expand author, then we will receive new error:
URI: https://localhost:44387/api/Books/2?$expand=Author

EDM (CSDL) Model

<?xml version="1.0" encoding="utf-8"?>
<Schema Namespace="MyNamespace" xmlns="http://docs.oasis-open.org/odata/ns/edm">
	<EntityType Name="User">
		<Key>
			<PropertyRef Name="Id" />
		</Key>
		<Property Name="Id" Type="Edm.String" Nullable="false" />
		<Property Name="Name" Type="Edm.String" />
	</EntityType>
	<EntityType Name="Book">
		<Key>
			<PropertyRef Name="Id" />

		<Property Name="Id" Type="Edm.String" Nullable="false" />
		<NavigationProperty Name="Author" Type="MyNamespace.User" />
	</EntityType>
	<EntityContainer Name="Container">

		<EntitySet Name="Books" EntityType="MyNamespace.Book">
			<NavigationPropertyBinding Path="Author" Target="Users" />
		</EntitySet>
	</EntityContainer>
</Schema>

Expected behavior
The Edm model is loaded and all odata functions are working as expected.

Notes
The same behaviour using CsdlReader and CsdlWriter.
$metadata endpoint works after loading through file.
