Perhaps Naruto is framed for a crime he didn't commit. The villagers, quick to believe the false accusations, turn against him. Feeling betrayed by the very people he once swore to protect, he then decides to betray Konoha in return. For example, if he was wrongly accused of assassinating an important figure in the village.
One possible reason could be that Naruto discovers some dark secrets within Konoha. Maybe he finds out that the village elders have been using him all along, not truly caring about his well - being but only his power as a Jinchuriki. This realization could be so shocking that he decides to turn against the village.
Another scenario could be that an outside force, like a powerful enemy, convinces Naruto that Konoha is not worth protecting. They might show him a vision of a future where Konoha becomes a tyrannical regime or is responsible for mass destruction. This could sway Naruto's loyalty and lead him to betray the village.
