A very bizarre issue just started happening recently (Jan 2025). Anytime I tried to edit my keymap in IntelliJ, the entire application would crash.
The fix ended up being:
- Open Help > Edit Custom VM Options..
- Add this line:
-Dsun.awt.mac.a11y.enabled=false - Restart IDE (File > Invalidate Caches > Just Restart)
Interestingly enough, I passed the crash log to Claude and asked what might be happening, and Claude mentioned that some interaction with the Accessibility system was likely the culprit!
I don't know what the root cause was, but sure enough the a11y keyword confirms that it was some strange interaction with the MacOS accessibility system.
Of course, I didn't come up with this solution out of thin air. I dug it out of this YouTrack bug report
