Your file is remembering your old choices and not letting you proceed because it thinks you've already exceeded the maximum number of times you can choose a route.
You have to start with a completely new file by choosing "New Game" at the beginning. Not just "Restart." If you're playing on browser I'd clear the cookies + cache. If on the Itch.io app, you could try deleting and reinstalling too. Let me know if this doesn't work!
