What's Wrong?

[BUG] Claude Code desktop app not working. I've had it previously installed and used it fine. Today it bounces once in the dock then disappears. I removed and reinstalled a fresh version today, and it is still doing the same. I'm using macOS Tahoe 26.5.1 on a M1 MacBook Pro.

What Should Happen?

I just need the app to open on my computer.
