STM32CubeIDE updated stlink on a stm32H743-EVALv2 board to V3J4M2, but then is unable to program the board.
Was able to program the board previously, but today after updating my STM32CubeIDE, it refused to run debug until I updated the stlink on my dev board.
But upon doing so, it gave these error. Essentially meaning I cannot program my dev board.

I am running this IDE on a mac on MacOS catalina. Oh and btw I still cannot run latest STM32CubeProgrammer on mac, even after updating java to latest version.
