the Built-in LED of the STM32f103C8 which is connected to PC13 stays ON even on an empty sketch. what is the solution for this issue ?

Have you tried setting PC13 as OUTPUT and HIGH? The LED is active low I think. So it's ON when you set the pin LOW. With an empty sketch, I'm not sure what the pin is doing. Maybe floating?
