Lack of toolchain is one problem, although I think that there are alternative toolchains out there that are quite feature-rich and could definitely achieve feature-parity with the web ecosystem, if only there was enough interest in using them.

JavaFX, even though it's outdated, is quite up to the job of replacing most Electron-based UIs. Qt is definitely extremely powerful, but has the drawback of being tied into the C++ ecosystem which seems rather dated now. Even some hobbyist efforts are worth mentioning in this category: AvaloniaUI (in the C# ecosystem), HaxeUI & FeathersUI (both in the Haxe ecosystem and building on game engines).

I think, the bigger problem is sourcing developers. Web developers are comparatively cheap and abundant, so a commercial entity is always going to have trouble justifying hiring a comparatively expensive and difficult-to-find developer in the C#, ObjC/Swift, or Java ecosystem, when the job can also be accomplished by a web developer.

You know, I thought I was a fool for writing my apps in JavaFX... but after trying many other things, it seems it's up there with the best of the bunch.

My non-trivial app can be built with jlink to be a no-dependencies on JVM binary for all Operating Systems.... each of which sits at just 30MB... and when run, it needs around 60MB of RAM, which is a lot but I am yet to find a multiplatform UI toolkit that delivers much less than that... except for some toy frameworks which can't really be used for realworld apps.
