Configuration Manager Tool 2020 - "No matching constructor found on type" error when launching the tool

Issue
When first launching CM Tool 2020 on a server (usually older versions of OS) it will ask for .NET 4.6 to be installed as it is not present. After installing the .NET and rebooting the server the CM Tool will still fail to open and will throw the following error:
"No matching constructor found on type
'ConfigurationManager.ViewModels.ConfigurationManagerVM'. You can use the Arguments or FactoryMethod directives to construct this type."
