I noticed that both of the examples you mentioned being sick or tired of is building a next.js app app for a pdf based product and assembling react apps for arbitrary companies. Have you thought about doing something other than frontend web dev? I know that's the hotness right now and that's the easiest path to get you jobs/money, but there's a variety of roles in software eng like web backend, data engineering, and even to other related disciplines like data science (with some learning curve), dev ops, embedded systems, etc. If you feel burned out from software engineering altogether, try using your expertise in other types of projects. For example if you enjoy making videos and teaching, make some Youtube videos to teach code or app building. Likewise if you enjoy music, you can do that instead.
