When I try to hand in the quest from the Headmaster, my game freezes. I verified the files. I don't know what else to do.

I entered the hole visible in the screenshot after landing, but the spot I get placed upon exiting makes it impossible to reach the boat again. This happened in the first Sapphire Town quest from the captain in my camp. https://ibb.co/bPc4RLt

After getting a lunchbox I remembered some lady wanting a fruity snack a while ago. After giving it to her, she gave me a lute in return. Now what?
