One possible reason could be jealousy. Maybe Albus feels overshadowed by Harry's fame and achievements. Another reason might be some misunderstanding between them. For example, if there were miscommunications or false rumors spread about Harry that Albus believed.
It could be that Albus has different ideals or values compared to Harry. Harry might represent a certain way of life or set of beliefs that Albus doesn't agree with. For instance, if Harry is very much into traditional wizarding ways and Albus is more of a rebel and wants to change things, this could lead to hatred.
Perhaps there is some family issue at play. Maybe there was a rift in the family that made Albus resent Harry. It could be related to how Harry interacted with Albus's family members or decisions Harry made that affected the family in a negative way in Albus's eyes.
