Gimble works, screen has small swirling icon on screen, But No Picture

Took Drone out to fly after 2 yrs. with no acitivity. Everything seems to work but

the app shows a black screen, with small swiriling icon like it is loading the Cameras

view, but just continues to swirl,…….. no picture. Gimble works fine. When I snap

a pix, I hear the “snap” and the available pix count lowers by one.
