Olympus XA3 Film Camera Not Working

Cosmetic Condition: 7/10
It shows signs of use.

Optics: 10/10
Viewfinder is bright and clear.

Mechanics: Needs repairs
The camera is stuck in self-timer mode. It works, but there’s a 10-second wait and beep sound between pressing the shutter and the camera taking the shot. All other camera functions work well. Shutter and diaphragm operate properly. Frame counter and self-timer work.
