As I said in a previous comment, please share your savedata on my Discord if you don't want to share it publicly. I'll help you find the problem. I know you're a beginner, and the game's story is very complex, with many unexpected twists and turns, which is why I created a walkthrough to make things easier. I don't know if you skipped every quest or if you didn't follow the order of the pages. The walkthrough may seem random, but everything is very clear with the additional explanations on each image; that should make things easier. If it's still difficult, I'll provide more details (if I have time to fix it).
