thanks for your patience. it looks like what happened was that a new simulator build was uploaded via our ci service using the same version name so it overwrote the previous one, so anyone who had downloaded it before was fine but new downloads would break.

👇 to resolve this issue 👇

stop expo-cli
run expo client:install:ios
it should prompt to install 2.16.1
say yes
try loading your project
if that doesn’t work, stop expo-cli and clear ~/.expo (rm -rf ~/.expo will do the trick)
try loading your project again

can you try uninstalling and reinstalling it?

I did multiple times, no luck though.

so, to clarify, you uninstall the app on your device, then go to the store and reinstall it, and then when you open it you see the error screenshotted in the original post?

I used iOS simulator. I deleted the app, re-installed it, and when I opened it I saw that error. I tried to reset the simulator too, but same error occurred.

I have the same issue on iOS simulator. When I click multiple times on “Run iOS Simulator” it eventually opens. It’s not a fix, but a way to ‘workaround’ it.
