Trying to post it in forum but gets rejected so i am trying to notify you from here.
file Microsoft.Bcl.AsyncInterfaces you are using is version 7.0.0.0 but exchange created the file C:\Program Files\Microsoft\Exchange Server\V15\Bin\GenericAppPoolConfigWithGCServerEnabledFalse.config
that has a redirection to version 8..0.0.0 and system totally fails
This also happen for two more files
System.Text.Encodings.Web and System.Text.Json

Tried replacing for testing the files with the ones having the 8.0.0.0 version from inside C:\Program Files\Microsoft\Exchange Server\V15\Bin\ folder and seems to open, but i also get errors creating users etc
