how the hell do you catch fish it isnt working

I'm sorry but this doesn't look like it was made by an actual artist; it looks like AI art.

The artwork looks very good. Is it made by AI or an artist?

I cannot proceed from here. I can move without problem but cannot do anything to interact. Restarted game twice with no chamge. Help!

So, I'm trying to find all the collectibles throughout the castle. I can't select the book under the table in the library, it keeps kicking me out to the main hall. It's like all the location showings aren't in the correct area's. Can anyone help?
