Actually. If a state sues another state, this is the only case where the USSC is the court of original jurisdiction. Only the USSC can hold a trial on these questions. That is a hell of an idea.
Texas sued Michgan in 2020 and the USSC ruled every State is sovereign as regards appointment of electors, no State has standing to challenge another State’s process - and Texas is free to appoint whatever Electors they choose in November, so what happened in a NY court affects Texas not at all.
