Nucleo STM32F411 seems bricked

I am using a Nucleo STM32F411, without any hardware modification.

I am working on a project which involves only UART and Debug monitor interrupt, so my code does not write anything to flash nor to option bytes. Yet it seems that the board is bricked after running my firmware. I tried STM32_Programmer_CLI and STM32CubeProgrammer to erase the flash but both fail:

is there a way to recover the board ?

Hello,

Any low power mode used in your application?

Try to play with the CubeProgrammer options:
