Why processor STM32F103VC is blocked after tiring to run 'hello world' program in debug mode?

Hello,

I just started work with STM32CubeIDE and I have hardware with STM32F103VC microprocessor. I made a new project. I set the debugger in options (I use Segger J-link).

When I clicked on the debug the program (STM32Cube) frizzed. After that I tried second time with another options but than i even can't connect to the processor and it's bricked, I can't even flash with hex.

I check with J-link commander and I can't establish communication with microprocessor. The Bootloader is blocked.

Can I unlock the processor now?

But most important is what to do to run the program correctly via STMCubeIDE? I don't want to lock another microprocessor trying by myself.
