This is an error now making the rounds in China. See a 12-part series discussing the matter here:

This view also ignores the anhypostasis and enhypostasis of the Incarnation.
Our Lord was one
Person, two natures. It was the Second
Person of the Trinity, God the Son, Who assumed a human nature. That
Person did not assume another person, only a
nature, else now we would have two persons, not one
Person. The fully divine Son is the person who took upon full humanity and remains the
one Person of the God-man. The human nature of Christ, although not itself an individual, is
individualized as
the human nature of the Son of God.
Before it (peccability) is raised up as an issue, Persons
act, natures
are. Divinity is sinless. Jesus has a divine nature. "
I and the Father are one." God cannot sin. Therefore Jesus cannot sin. Nor can it be argued that because Jesus has a human nature it is possible for Him to sin, because, as noted, only Persons act, not natures. Our Lord had no original sin to deal with, and therefore He was suitably empowered by nature to obey God's will, just as was Adam before the fall. We need to remember that
sin is not essential to the human nature qua nature.
