This bug will have been fixed in the broker interop https://github.com/AzureAD/microsoft-authentication-library-for-cpp/pull/3807/files (private repo) but not yet released.

@ashok672, @iulico-1 - regular release goes out every Thu of every month, so next one is scheduled on Dec 7. Happy to help with an out of band release if needed by partners.
