Ok and what happen in the time between when it did work and that when it didn't?

Make sure you have the debugger connecting in SWD mode, and Under Reset option is selected. It really isn't necessary to attach images of common error messages, it doesn't provide any context to the question. See also the mountain/sun icon for inlining images to a post.

I didn't change any hardware setting or compiler setting.

I just did disconnect and connect, that it. After that debugging led start blinking.Whenever i connect board to pc then led is starting to blink and not able to flash.

Suggest you try different connectivity options with the ST-LINK Utilities, and confirm if you can connect and fully erase the part.

Pulling BOOT0 High will allow the STM32 to boot into the System Loader instead of User code.
