How can Protestants claim to be guided by the Holy Spirit in contradicting Marian Dogmas?

The Catholic Church has four Marian Dogmas and claims that the Church was guided and its teaching was inspired by the Holy Spirit. CCC95 says, > It is clear therefore that, in the supremely wise arrangement of God, sacred Tradition, Sacred Scripture and the Magisterium of the Church are so connected and associated that one of them cannot stand without the others. Working together, each in its own way, under the action of the one Holy Spirit, they all contribute effectively to the salvation of souls. *Pastor aeternus* teaches that the Pope is guided by the charism of the Holy Spirit and upheld infallibility in proclaiming Church Dogma. > We teach and define that it is a dogma Divinely revealed that the Roman pontiff when he speaks ex cathedra, that is when in discharge of the office of pastor and doctor of all Christians, by virtue of his supreme Apostolic authority, he defines a doctrine regarding faith or morals to be held by the universal Church, by the Divine assistance promised to him in Blessed Peter, is possessed of that infallibility with which the Divine Redeemer willed that his Church should be endowed in defining doctrine regarding faith or morals, and that therefore such definitions of the Roman pontiff are of themselves, and not from the consent of the Church, irreformable. — [Pastor aeternus](https://en.wikipedia.org/wiki/Pastor_aeternus) How come the Protestant and Christian denominations or Bible alone believers who oppose these Dogmas claim that they are also guided by the same Holy Spirit? Is the Holy Spirit that guided the Catholic Church in proclaiming the Marian Dogmass the same Holy Spirit that were inspiring Protestant and Christian denominations to oppose it? How can the Protestant defend themselves on this obvious contradiction, knowing fully that there are no Protestant pastors and believers who can claim infallibility in their scripture interpretations?
