Thank you. You've quoted the correct text. I have posted it here twice myself in order to demonstrate to semi literates like yourself that the outcome of the election has been decided. Let's take another look at the clause:
"The President of the Senate shall, in the presence of the Senate and House of Representatives, open all the certificates and the votes shall then be counted; -- The person having the greatest number of votes for President, shall be the President, if such number be a majority of the whole number of Electors appointed; and if no person have such majority, then from the persons having the highest numbers not exceeding three on the list of those voted for as President, the House of Representatives shall choose immediately, by ballot, the President. But in choosing the President, the votes shall be taken by states, the representation from each state having one vote; a quorum for this purpose shall consist of a member or members from two-thirds of the states, and a majority of all the states shall be necessary to a choice."
Show us the language that empowers state legislatures to do what you say. Of course there is none, and the Vice President's only duty under the Article is to supervise the "count". He doesn't get to change the count. Joe Biden being "the person having the greatest number of votes for President, shall be the President".
Perhaps it's your weakness with English that keeps you from realizing that the election has been decided.
