Bug: Standalone app stops responding to changes after some time

Steps to reproduce the behaviour

1. Have the standalone Focalboard app installed for some time.
2. Attempt to add a new card, edit an existing card, or move a card.
3. Nothing changes. If I reopen the app, I'll see my changes applied.

Expected behaviour

The app doesn't seem to lock up randomly

Edition and Platform

• Edition: Personal Desktop (Mac App Store)
• Version: 0.15.2 (33)
• Browser and OS: MacOS 12.4

Screenshots

Additional context (optional)

I'm not sure if this is in anyway relevant, but this version of the app still shows "Mar 2022" next to the Focalboard logo despite being a newer version. I remember mentioning this a while back, and I think this issue was known, so I'm not sure if I've gotten stuck in some weird state where the app isn't updating correctly.
