Does cursing God and religion during a dispute break the fast in Ramadan and necessitate expiation by fasting one day or two consecutive months after repentance and remorse?

Islam is a prerequisite for the validity and acceptance of acts of worship, as Allah Almighty says: (Say: "Spend willingly or unwillingly; never will it be accepted from you. Indeed, you have been a defiantly disobedient people." And what prevented their contributions from being accepted from them was only that they disbelieved in Allah and in His Messenger). Therefore, whoever disbelieves and apostatizes during their fast has invalidated it, and they must make up that day if they return to Islam. As for expiation, it is only obligatory for those who break their Ramadan fast by sexual intercourse.
