    The device descriptor in the Ports menu tells you a lot too. Get a Genuine Arduino, or a BlackBox (see https://docs.openbuilds.com/blackbox)

    Possibly your chinese "arduino" doesn't have the right bootloader or is just junk. Money saved = time spent.

    You weren't trying to connect (button on main toolbar) according to your Screenshot. You were trying to Reflash firmware (from Wizards and Tools)

    Then your controller is either fried, or doesn't run Grbl 1.1

    according to the github for makerbase it should support GRBL, but the message you got indicates it does not have a bootloader (this helps things like OBControl and Arduino install firmware through the USB port).

    if it is this board
    MKS Gen V2.0 DLC GRBL Controller - Makerbase
    then it looks like it has an ISP port so you can program it using an ISP programmer like this one
    2.38US $ 11% OFF|10 Pin to 6 Pin Adapter Board USBASP USBISP AVR Programmer USB ATMEGA8 ATMEGA128 ATtiny/CAN/PWM 10Pin Wire Module with Cable|avr programmer|set 6usb board - AliExpress

    You can choose to install the bootloader (from Arduino IDE) and then OBControl can load GRBL for you (without the USBASP board, just USB), or you could load one of the GRBL .hex files directly.
    I would load the bootloader, it makes later updates much easier.
