Installing extension problem

Hi,

 

I have clean installation of Windows Server 2022 (include all updates) and Azure DevOps Server 2022 Patch 3.

I am trying to install some extensions from Marketplace (I have tried many different extensions), but I am getting the same validation error:

 

Extension validation error

 

Could not load file or assembly 'System.Web.Mvc, Version=4.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

 

Has anybody encountered this problem ? 

Thank you
