Cannot open .xcworkspace created with expo (empty project)

Creating a testapp with expo and then trying to open in XCode just hangs.

npx create-expo-app TestApp
cd TestApp
npx expo prebuild
cd ios
open TestApp.xcworkspace

This used to work, but I think stopped after something got upgraded to latest, because I tried uninstalling and reinstalling latest XCode, exp, pod and result is still the same. Please Help!
