None.
Nada.
Nothing.
Do you mean no Scriptural support or just none that you agree with? There is a difference.
Where are the Bible verses that state that Mary was without sin?
It is contained in the third chapter of Genesis and the first chapter of the Gospel of St. Luke.
That she was kept free from the stain of sin?
Genesis 3 and Luke 1.
That she bodily ascended as Christ did?
The Catholic Church has NEVER claimed this.
That she is the mother of the church?
John 19:27.
That she is ruler of hell?
The Catholic Church has NEVER claimed this.

John 19:26 “When Jesus saw his mother and the disciple whom he loved standing nearby, he said to his mother, “Woman, behold, your son!” 27Then he said to the disciple, “Behold, your mother!” And from that hour the disciple took her to his own home.”
These verses just deal with Jesus discharging His responsibility to care for his parents as the oldest son by providing for her care after His death. This does not indicate that she is the mother of the whole church.
***********************************************************
I read nothing in Luke 1 or Genesis 3 that indicates that Mary was without sin.
The sin nature comes through the father, not the mother. The reason Jesus was born sinless is that He didn’t have a human father; god, who is sinless, is His father. It’s irrelevant whether Mary had sinned or not. His being in her presence would not contaminate Him any more than His being in the world and touching lepers contaminated Him.

Mary is crowned Queen of heaven and earth, dispenser of all graces . . .
4 - She became Queen of Purgatory, where she exercises her power as mediatrix in behalf of these suffering souls.
8 - She became Ruler of hell, that trembles at her slightest gaze and is defeated by her power.
