Aversion to fiction books

As I’ve gotten older I’ve become averse to fiction books, I can’t pinpoint why but it’s just hard for me to latch on to it. What if I don’t like the story, or the character, or the prose, ect and waste my time or something upsets me.

I like how with non fiction i know the start and end to the story, the fun is filling in the gaps. Fiction books though I just have to go off a premise and a vibe. I also don’t like books based off movies I’ve seen, so those aren’t a safe choice either.

I’m wondering if anyone has any tips on how to start getting into fiction books? I’m thinking maybe historical fiction might be worth a shot.
