Hello. I have a question about STM studio. my code works properly on stm32 and there is no error. I want to see my data on stm studio. after importing my data, when I want to run I get "Error opening ST-link connection". what's the problem?

Can other software use the ST-LINK connection? Try STM32CubeProgrammer, STM32CubeIDE? If not, reinstall the ST-LINK drivers.

Note that STM Studio has a successor: STM32CubeMonitor. Maybe that one works better for you.
