Having just downloaded and installed the latest version of Hue Essentials for the Mac today (11/6/2022), successfully logging in with my Hue account, then selecting the menu option “Hue Essentials”, then “About Hue Essentials” produces a small message window showing “Error” on the header, with text “Invalid destination: a@2b87d1b5” and an OK button. Clicking the OK button immediately terminates the app. My Mac has the very latest version of macOS and all applications as of today’s date (11/16/2022) and the problem is repeatable. The app itself performs as expected once restarted though, and seems to be an excellent product.
