Harmony 17 doesn't work on Monterey

I just updated my OS due to port issues on my MacBook and now Harmony Premium 17 no longer works. Any suggested fix. Please! I am in the middle of a college assignment!

Maybe try updating Harmony 17 to the latest build or upgrade to Harmony 21, reinstall an older macOS and stick with TBH17, contact support and see if they can do anything for you.
