(with the slow courts), based on what Paxton did during the 2020 election suing other states because he didn't like how they ran their elections - the courts (including the SCOTUS) threw the suits out.
In essence, a state doesn't have that kind of authority over how another state handles its affairs.

WASHINGTON (AP) The Supreme Court has rejected a lawsuit backed by President Donald Trump to overturn Joe Bidens election victory, ending a desperate attempt to get legal issues rejected by state and federal judges before the nations highest court and subvert the will of voters.

Fridays order marked the second time this week that the court had rebuffed Republican requests that it get involved in the 2020 election outcome and reject the voters choice, as expressed in an election regarded by both Republican and Democratic officials as free and fair. The justices turned away an appeal from Pennsylvania Republicans on Tuesday. On Monday, the Electoral College meets to formally elect Biden as the next president.
Trump had called the lawsuit filed by Texas against Georgia, Michigan, Pennsylvania and Wisconsin the big one that would end with the Supreme Court undoing Bidens substantial Electoral College majority and allowing Trump to serve another four years in the White House.
In a brief order, the court said Texas does not have the legal right to sue those states because it has not demonstrated a judicially cognizable interest in the manner in which another State conducts its elections.

Whenever you DO see states "cooperate", they have MOUs (Memorandums of Understanding) and other agreements (like for extradition) in place to authorize it.
