I updated the freeze repro project some. Instead of big maps it is now using many more, smaller maps. I did it to confirm to myself that the size of the maps is not what matters. TL;DR; The repro is now like so: 1. Have the debugger connected 2. Save changes to a file which requires enough definitions from other namespaces. Freeze! You’ll see [React DevTools] Connection to RN closed in the debugger and the app stops responding to taps. (Sometimes it crashes instead).
