runtime: System.Text.Json Serialization Regression in NET6 (Net5 worked)

Description

I Serialize a Class with an IQueryable in it, looks like this:

public class WebsocketResponse { public object Response {get;set;} }

Reproduction Steps

Test Project:

use following 2 nugets:

<PackageReference Include="linq2db" Version="3.5.1" />
<PackageReference Include="Microsoft.Data.Sqlite.Core" Version="5.0.11" />

and following code:

      using LinqToDB.Data;
      using System.IO;
      using System.Text.Json;
      
      using (var dc = new DataConnection("Sqlite", "Data Source=:memory:"))
      using (var ms = new MemoryStream())
      {
          using (var writer = new Utf8JsonWriter(ms))
          {
              JsonSerializer.Serialize(writer, new Response { Result = dc.GetTable<DbTable>() });
          }
      }
      
      public class DbTable
      {
          public string A { get; set; }
      }
      
      public class Response
      {
          public object Result { get; set; }
      }

Expected behavior

Serialization should work as it did before.

Actual behavior

System.NotSupportedException: ‘The type ‘LinqToDB.Linq.Table`1[…]’ can only be serialized using async serialization methods.’

Regression?

Yes, this did work in Net5
