Following an argument with my daughter about the choice of her studies, I want to cancel the donation I gave her 5 years ago. Is it possible?

No. Indeed, when you donate, it is irrevocable. The donated property enters the patrimony of the donee (the one who receives the property) and you cannot recover it.
However, there are legal exceptions to this irrevocability (article 953 of the Civil Code): when the donee has not fulfilled the obligations (we speak of charges) provided for in the deed of gift (article 954 of the Civil Code) or has been guilty of ingratitude (article 955 of the Civil Code), in particular if he has refused any financial support to the donor in need. The reason for your disagreement does not allow you to recover the property given to your daughter.
