Thanks for the report. This is due to an oversight during the code signing process of the 6.1.36 Extension Pack for macOS. We are working on addressing this presently.

Confirming the issue is now resolved by updated extension pack on Downloads page.

Thanks to the Development team for the quick (same day) action.
