Latest IntelliJ completely broken?

My 45 line pure Java program with 0 dependencies takes a whole 5m 12s to build. If I cancel this obnoxiously long build, it sits at "Stopping build" for several minutes. If I try to debug and set a single breakpoint in my program, the debugger will either timeout or take about 15s to execute every line of code.

I use Android Studio regularly and my Android Studio app builds take seconds to build, and I've never had any lag with debugging. IntelliJ is literally unusable right now, and I have no idea what is wrong. I'm on build #IU-193.4778.7, the latest as of this post. Is there some major fix I can't find on Google? Is this build just truly terrible? I guess I should turn-off auto-update from Toolbox if IntelliJ is just going to kill itself like this.
