Tropy frozen and won't open project on Mac iOS

I tried to open my project today, and while Tropy says it’s open and running, the window doesn’t appear. And Tropy won’t restart or quit either. Is there a new update I need to download?

The issue seemed to resolve itself once I figured out how to actually make Tropy quit (command+option+esc on Mac) and opened my project first, rather than opening Tropy itself first.
