The IControllerFactory 'Munq.MVC.MunqControllerFactory' did not return a controller for the name 'Home'

Question

My client has legacy application based on ASP.NET MVC 2 Framework which runs well on WinSrv 2008 R2 VM. I've cloned this machine, changed IP, hostname etc. and this cloned machine was upgraded to newest WinSrv 2019 (first 2012, then 2016 etc.). The goal was migrate this app on new server for security reason. After migration I have noticed error which cause showing this information in browser: error information There is an entry in Event Viewer

This happens regularly until I refresh browser and then application works fine. I don't have access to documentation.
