Unable to manage Hide My Email on Mac after update

I use Hide my e-mail extensively. After updating all my devices to 26.2 I am no longer able to view Hide my e-mail on my Mac. I can manage it on other devices (iPad, iPhone). But when I try to manage it on my Mac I get the following message: Extension process `Apple Account(7821)` exited.

I tried logging out of iCloud, restarting my Mac, and logging back into iCloud. But the problem persists.
