Hi, I am trying to use SilkierQuartz v5.0.234 but I am getting a runtime exception

System.TypeLoadException: Could not load type 'Microsoft.Extensions.DependencyInjection.MvcJsonMvcCoreBuilderExtensions' from assembly 'Microsoft.AspNetCore.Mvc.Formatters.Json, Version=5.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

I am using dotnet core v5 in a hosted windows service with ConfigureWebHostDefaults
Would you have any suggestions?
Thank you
