So we have a Server 2019 that is failing DISM repairs, the reason why I was trying to run these repairs is there are a few issues that seem related to windows OS corruption, such as taking over 5 minutes for a user to login to a rds session, and the inability to repair appx packages resulting in our Office 365 installation being unable to activate.
