MusicBrainz Picard 2.11 consistently crashes on startup. The application fails to launch, presenting a crash report each time. This issue does not occur with MusicBrainz Picard version 2.10, which functions as expected on the same system.

Troubleshooting Steps Taken:

1. Reinstallation: I performed a clean installation of MusicBrainz Picard 2.11, but the issue persisted.
2. Testing on a Different User Account: I tested the app under a different user account on my Mac Pro. The application still crashed on startup, ruling out user-specific configuration issues.
3. System Updates: I verified that my Mac Pro is updated with the latest macOS 10.14 patches. (It's the latest version that will run on this machine.)
