I work at a place that ships an app to both Apple and Microsoft Desktops (we could even do Linux is there was ever any demand for it). We use this old thing called Java which still seems to work. I don't develop it though so I guess I don't have to worry about too much of my resume getting caught up with unfashionable languages (let's face the facts about what most tech these days is trying to advance - promotions - not the state of the art).
The only Java desktop app I've ever used (on any platform) without frustration was Slay the Spire, and it only passes because it's a game and doesn't require desktop integration of any kind.
Slay the spire is built using libGDX which provides a lot of cross platform support on top of Java. For platforms like Switch without JVM support it probably ships a compiled version without JIT.
