It sounds like a break from work life would be immensely helpful. Here's another alternative that I'd recommend.

You didn't mention taking any breaks / vacation during this period. Take a week or two off and see how you feel. If you feel you should go longer, do it. I'd strongly advise against going right into a 6 month break.

Good advice! However, I just got back from a week long vacation and still felt this way... I was hoping it was burnout, and that a vacation would do me well. But it's more a general unmotivation to keep working on this project.

A week is rarely enough time to expect a real mindset or perspective change, especially if you're not setting out with intent to do so. I'm not saying you shouldn't quit, but if you wanted to give yourself a chance to avoid burnout, perhaps discuss the possibility of a longer sabbatical with your employer. As someone who's spent some time on full-time side-projects, full-time employment, and in-between, the grass isn't always greener.

If its around the project, then change projects if you can!
