Reformation avoided if the Roman Catholic Church shatters?

Supposedly say that the Roman Catholic Church falls apart and turns into national churches. Maybe if Mehmed II lives longer and conquers Rome. Does this butterfly away the reformation entirely or are some Protestant groups still coming to existence? Calvinism for example, would it come to existence if the Papacy moved to Avignon and several new national Churches were founded? Or is it entirely butterflied away?

I think it may still happen but it would not be the cataclysmic event it was IOTL. You would entirely remove the incentive for national leaders in places like Britain and Scandinavia to go with the flow to get religious independence from Rome. However, you might still get something in the Holy Roman Empire if people wanted to defect from the German Catholic Church.

While I think a Ottoman Conquest of Rome are a bad joke, let’s for argument say it the Ottoman succeed, well in that case the Papacy just move elsewhere until Rome are recaptured. But yes it would likely butterfly the Reformation away, because a Papacy in Exile will not do the things which alienated large part of the general population, and with the secular power of the Church weaken, the princes of Europe will have less reason to wanting to break it, so the Reformation will instead of being a large mass movement simply be few heretical groups like what we saw in the Middle Ages.
 
I think one needs only to look at the ecclesiastical history of England to get the answer. Henry VIII broke with Rome yet Protestant theology didn't truly begin to influence the Anglican church until Elizabeth I's reign. While Catholics were an effective bogeyman for Church and state, the biggest source of conflict ended up being with Nonconformists who did not want state control of their churches. A major source of immigrants to early America was not Catholics, but Protestant dissenters fleeing the religious turmoil back home. This would have happened regardless of the Papacy's fate in the 15th/16th centuries.
 
If there is no "universal" Church there will be no reformation. Many of the issues where regional, and will have to be dealt with, but would then happen in a more regional matter. It would look more akin to otls orthodox churches .
