I have the same issue and I have OneDrive, SnagIt, Postgres, F-Secure and the rest are Apple items. Clock is gone. This is a bug dude and the sandboxing is enough to prevent one app from stepping on another. It happened after the latest update to Sonoma so don't treat this as the user's fault. "Oh you're just holding it wrong" ...the apps there were the same before an update of versions of Sonoma. Not a new OS, but new versions of Sonoma. So they worked, the clock worked, then it didnt. It is a bug.
