For example: Biden gets sworn in. Then, prior to Biden dismissing the the Trump cabinet, the Trump cabinet uses the 25th amendment to relieve Biden, Harris, and other members of Congress of their duties for high crimes and misdemeanors (treason, election fraud, crimes against humanity, etc.).

Your theory has two fatal flaws. First, it requires the Vice President to be involved. The Vice President in this scenario would be Harris. Unless you are claiming that Kamala Harris is a White Hat... Second, the 25th Amendment only deals with vacancies in the Offices of the President and Vice President. Members of Congress cannot be removed through the 25th Amendment.
