fuck visual studio

I still hate Android Studio :( :( :(

Worked all morning on my project, debugging, no problem.

Now all of a sudden it crashes whenever I try to debug. java.lang.ClassNotFoundException - random classes.
But it runs fine if I just run the app.

I reverted to my last working commit, and it still does that. I restarted my computer. No luck.

I disabled Instant Run. No luck.

I tried to upgrade gradle to 3.3 - no luck. That's the extent of stack overflow suggestions for similar errors.

I am stumped. What has changed in the middle of a work-session when I have not changed any settings in the IDE, have not updated anything.

Aaarrgh!
