I'm definitely seeing this too. In my case, clicking the i icon and going to Exception shows:
Exception Type: SIGTRAP
Exception Codes: TRAP_TRACE at 0x10c10744e
Application Specific Information:

Even running defaults delete com.71squared.focused

I thought it had to do with relying on auto-save to have 20-ish untitled documents maintained, but now it's looking like even from a fresh start nothing helps.
Among other things, this also seems to be messing up something so that Undo/Redo just don't work, they stay disabled and never enable, nor does the Undo item change to reflect what there would be to undo, making it look like the undo manager isn't hooked up at all. I went through a number of upgrades when Typed was Typed, and nothing like this happened before. Having this sort of thing happening to a productivity tool is very disconcerting.
