Final Cut Pro X: May stop responding at "Restoring the window layout" or open to a gray window
In some cases, Final Cut Pro X may stop responding on launch while "Restoring the window layout" or may open to a completely gray window.
To address this issue, remove the Final Cut Pro Layouts folder. Once this folder is removed, Final Cut Pro X will create a new Layouts folder on launch.
- In the Finder, hold down the Option key and then choose Library from the Go menu.
- In the Library folder that opens, go to Application Support > Final Cut Pro.
- Drag the Layouts folder from the Final Cut Pro folder to the Trash.
