In some fanfictions, it could be because of a prophecy. She might believe that Naruto is fated to bring destruction, and in an attempt to prevent that, she betrays him. Or she could be jealous of Naruto's relationship with other friends or comrades. If she feels that Naruto values others more than her, she might be driven to betrayal out of spite and jealousy.
One possible reason could be that she is influenced by an enemy. Maybe the enemy has some sort of leverage over her or has brainwashed her into believing that Naruto is a threat. Another reason might be a misunderstanding. For example, she could misinterpret Naruto's actions as being unfaithful or harmful when in reality he has good intentions. It could also be due to her own insecurities. If she feels overshadowed by Naruto's popularity and power, she might betray him to assert her own identity.
She could be forced to betray Naruto for the safety of her family or loved ones. In the world of Naruto, there are often threats that can be used against someone. If an evil force has her family hostage, she may have no choice but to turn against Naruto. Or perhaps she discovers a dark secret about Naruto that she can't accept, like some sort of hidden power or connection that she believes is evil, even if Naruto is not using it for wrong purposes.
One possible reason could be that she was forced to betray him. Maybe an enemy got to her family and threatened her to turn on Naruto. For example, in the Naruto universe, there are many powerful villains who would stoop to such tactics.
It could be due to a power imbalance. If Naruto's power as Hokage makes her feel overshadowed or unimportant, she might be led to betray him. Also, perhaps she discovers some long - hidden secret about Naruto that she can't forgive, like a connection to a past enemy or some dark side of his shinobi past that he has kept from her.
One possible reason could be a misunderstanding. Maybe Naruto's newfound power is misconstrued as a threat. For example, if he discovers a new jutsu that the Konoha 11 don't understand, they might think he's going to use it against the village. Another reason could be the influence of an outside force. An enemy could manipulate the Konoha 11 into believing Naruto is a traitor, perhaps by forging evidence or using mind - control techniques.
Well, one reason could be jealousy. Maybe his friends envy his fame or special abilities. Another could be misinformation. If they are fed false information about Harry, they might turn against him. For example, if someone convinces them that Harry is secretly working for the enemy.

One possible reason could be jealousy. Maybe his friends are jealous of Ash's success in his Pokemon journey. For example, if Ash wins a big tournament and gets all the fame, his friends might feel left out and betrayed. Another reason could be a misunderstanding. Ash might do something that his friends misinterpret. Say he makes a deal with an enemy in order to save his Pokemon, but his friends don't understand the situation and think he's turned on them.
One possible reason could be political intrigue within Konoha. Maybe there are certain factions that see Naruto and Hinata as threats to their power. For example, they might be afraid of Naruto's influence due to his status as a hero and Hinata's connection to the Hyuga clan. Another reason could be a misunderstanding. Perhaps some false information is spread about them that makes Konoha turn against them.
Well, it could be that Naruto's friends are influenced by a dark power. This power could twist their perception of Naruto, making them see him as a threat instead of a friend. Or perhaps there's a prophecy that Naruto is supposed to be the cause of some great disaster, and his friends, in an attempt to prevent it, decide to betray him. It's also possible that a new character enters the story and sows seeds of discord among them, leading to the betrayal.
