"A black display issue: Hello, I need help with a display issue on my MacBook Pro M4, IOS Golden Gate. The screen suddenly turns black when I click or open Finder. However, the MacBook itself is still running. The cursor can still move, and the Dock may still be visible, but the main display becomes black. The problem happens unexpectedly and has occurred more than once. "
