STM32F107VCT6 core is locked-up after programming

There are two identical controllers with STM32F107VCT6. One of them is programmed, and another one is not. Memory protection is disabled. I haven't the original program project, and the task is to read and save program from the first controller and download it to another one. Programmer is ST-LINK V2 isol connected via SWD. Programming is successful, but controller can't start. ST-LINK Utility says "Unable to run application", and Cube Programmer shows a warning "The core is locked-up". Reset doesn't help. Tried to use different BOOT0 and BOOT1 states, but there is no result. Where is the problem and how to make the controller run?

Try to power cycle. Many debug units are not affected by reset.
