Many here point out, and rightly so, what an abominable mess UI frameworks have been on Windows for quite a while.

That being said, I'd point out that the situation has been (and still is) unfortunately far from satisfying on the cross-platform and open-source side as well: GTK has also been a mess for quite long; Qt has - aside from the bloat - an increasingly repulsive licensing model for professional use (too bad the hopes from the early Nokia adoption days got smashed by MS mole Elop and the later owners of Qt), …

… and while there are some nice solutions for specific niches (e.g. Dear Imgui), the overall situation in general-purpose cross-platform native UI frameworks looks quite bleak and unsatisfying imho. There's a huge gaping opening for a permissive-licensed open-source cross-platform UI/Widgets framework that compiles to native, has a good set of widgets and gives access to Vulkan contexts for 3D rendering.

People like to hate on Electron and React Native (because web bad!!!!) but tend to fail to realize there’s basically no alternative if you want to be platform flexible.

Microsoft could’ve made a real impact in this area with a great advantage to themselves, but both efforts I’m aware of were so half hearted they could never have worked out.
