What's Wrong?

Description: Claude Desktop (v1.1.5368, macOS arm64) freezes on startup when a
scheduled-tasks.json file exists in ~/Library/Application
Support/Claude/claude-code-sessions/<account-id>/<org-id>/. The main process
pegs at 100% CPU and the UI becomes unresponsive.

Resolution: Removing scheduled-tasks.json from the claude-code-sessions
directory resolves the freeze immediately. All other session files load fine.

Environment: macOS 26.3.1, Apple M4 Pro, Claude Desktop 1.1.5368

What Should Happen?

Claude should open and run the scheduled task.

   task, something goes wrong, resets, and loops forever.
