Critical rekordbox issues on multiple Macs — crashes, failed backup, and recurring relocate problems

Hi AlphaTheta Support,

I’m using rekordbox professionally at events, and recently I’ve been experiencing several critical issues that make the software unreliable during live performances.

Main issues:

1. rekordbox crashes approximately once every hour during use.
2. The “Backup Library” feature constantly fails and does not complete successfully.
3. Many tracks repeatedly require “Relocate” even after I already relocate them successfully. The same files lose their paths again and again.

Important details:

• I use Cloud Library Sync / cloud backup.
• The exact same issues are happening on a brand new MacBook that is only one week old, so it does not seem related to old hardware or a damaged computer.
• This started recently and did not happen before.
• The issues happen during live events and are seriously affecting my workflow.

I would appreciate help understanding whether this could be related to:

• Cloud Library Sync,
• database corruption,
• Dropbox/iCloud/external drive syncing,
• file permissions,
• or a known rekordbox issue.

Please let me know which logs, diagnostics, or database files you would like me to send.
