Anyone installing today's macOS 26 build (beta 2) should know that the Keyboard Maestro editor crashes on launch. The engine is still working in the background, but you can't access the editor.
I think it's related to some kind of Webkit change as other apps (like Raycast) are also crashing, and the stack traces look sinilar for both.
Thanks! I filed it already. It's an issue with loading fonts, which I assume is a regression and will be fixed. The workaround is to launch Font Book, go to the Advanced tab, and hit "Reset Fonts".
