Solution:

Get a USB-C to USB-C cable and plug it into another Mac• (host).

Download and install Apple Configurator 2• .

Put the MacBook with the issue into DFU mode• (right shift, left option, left control) + Power button - release the3 buttons after 10 seconds, keep holding power for another 10 seconds.

• Restore the MacBook from Apple Configurator 2.

• The latest OS will download on your host computer and push it to the MacBook in a 4 stage process.
