I am using Project Server 2019 on Premises with the latest Microsoft Update but there is an issues we faced in exporting from PPM to excel in PWA.
1. I logged in with System Account users and when i export things from PWA, or Site Settings users and other places from Resources it gives me error and when i checked in logs it shows error "System.Security.SecurityException: Requested registry access is not allowed." when i logged in with System Account ???
2. From the Project Site when i export things to excel its working. So this is another shock.
Just wanted to understand and resolve this issues as soon as possible.
