HELP.... Error in final launch sequence: Failed to execute MI command

[EGonz.11]

Hello 

I'm trying a project with a STM32L051R8T6 microcontroller and STM32CubeIDE, I already finished my code and tested in a board, everything worked fine . I've not modified the code, anf now I can't enter in Debbug mode.

​I​ tested the ST-Link with other of my projects and it is working fine, the problem is with this new development that I'm trying. I have three boards prototype and the error still occurring with all of them.

Please check the attached files with error message​.

Can you help me to solve?
