Electron doesn't look native, which a lot of consumers don't like. Others don't care. So, depending on your audience, it can be an extra hurdle that some like wxWidgets don't have.
Electron is difficult to get performant. You need to really think and test your perf. Qt, Tk, and a few of the others are much faster, much easier. And if you put in the same effort you need to put in for a fast Electron program, you can end up with blisteringly fast speeds.
Electron bundles are large to download. Some places this doesn't matter, others it does. (Think Australia, Africa and the like where tiny download caps exist). IIRC Qt, the biggest dependency, is about half the size of Electron. Tk and wxWidget are small, nuklear is just a header. It's tiny.
Electron is not good with touchscreens (or "harder to get right"), but more and more people have them. Kivy is great for that usecase.
Electron is "just code". Qt Creator and Lazarus' IDE are phenomenal for putting GUIs together. You'll be surprised how little code you need.
Electron is primarily JavaScript. Some people like that, others don't. If you want an easy language, you can use Python, or Nim. Want more control C or C++. Value both time and control? Go with Java.
Electron has its place.
If you have a really tight time-to-market window, or this is just a tiny personal project, and JavaScript is your "goto" language, then awesome. Use it.
But, the cross-platform GUI world is big. You have a dozen or so mature, stable, proven frameworks.
So if your project takes off, or you have the time to do things right, evaluate if any of these libraries, including Electron, fit your needs.
I said C/++ was more control, Java was a middleground between the two. Nim is easier, but its memory usage and performance are harder to be sure about, because it hasn't been around as long.
