My opinion is that the military will have to step in because leftists would not accept a SCOTUS ruling. They would not accept states decertifying the election results either.

Resident Biden will not step down w/out a fight. Once again the DIMocrats would be doing exactly what they had said POTUS would do - refuse to leave the White House. I expect massive shit hitting the fan at least for the first few days IF the election results are decertified and the military has to take over. After Katrina hit NOLA, there was chaos for a day or so until the military came in and settled things.
