Problem is you're competing in a saturated market (Electron, React Native for Windows and macOS) and already tested your positioning once with the KickStarter campaign. Finding a way to fund this is going to be an uphill battle, although I like the creative ideas amadeuspagel mentioned. Like anything else, find a niche somewhere (possibly related to performance/memory for clients not using React) and serve it with a modest upsell. But it's an enormous market, with entrenched competitors who don't need to make a profit on their offerings, so expect fierce competition all the way.
