If your product fails, do you usually keep the domain or just let it go?

I built a product backend in 2019. Unfortunately, it didn’t work out. But it’s a .ai domain with good domain authority. I’m not interested in working on that product or niche anymore. I was emotionally attached to it last time, but this time I want to let it go.

What do you think? What do you guys usually do in situations like this?
