Section 1. No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once. But this Article shall not apply to any person holding the office of President when this Article was proposed by the Congress, and shall not prevent any person who may be holding the office of President, or acting as President, during the term within which this Article becomes operative from holding the office of President or acting as President during the remainder of such term.

“No person shall be elected to the office of the President more than twice,” doesn’t say consecutively. It would take a HUUUUGE leap of logic to insert that word where it doesn’t exist. I’m sure someone will make the argument, but by the letter and the intent of the law, Trump is done after this term.

“and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once.” If Trump has a heart attack and dies before January 20, 2027, Vance would take over and serve 2+ years as President, meaning he could only be elected once for one four-year term.

The rest of Section 1 just means anyone who was in office at the time is grandfathered into the old rules (no limits).
