Could it be that you're at the point in your career where you've hit the limits of your own scalability? No matter how well you perform, you're always you. The single one of you. Carrying the burden of excellence, knowing people depend on you to know the answer can wear you out, i empathize with that. Maybe try finding a role where you aren't contributing individually, but where you are helping others become their own little centres of excellence. Find a new way to scale your abilities, beyond coding yourself. This might mean mentoring, leading a team, if you're up for it. This could be something novel and fresh to do, without entirely abandoning software.
