Fourteenth Amendment doesn't work. Trump has not been found guilty. As long as he keeps the trial 'open', by appealing, if he is found guilty, he has not done the insurrection stated by the 14th Amendment. At the Supreme Court level, the Justices will decide that there isn't enough evidence against Trump to find him guilty. In fact, they might even hand down a verdict that leaves Trump open to file against his opponents, and such with the success that they didn't have.
