Updated to Expo CLI 3.8.0 last night, completely broke the entire dev environment. I have rolled back to CLI 3.4.1, but now every time I try to run expo start, or expo publish, or anything else, I get this error:

_xdl(…).ProjectUtils.readConfigJsonAsync is not a function
TypeError: _xdl(…).ProjectUtils.readConfigJsonAsync is not a function
at configureProjectAsync (/expo-cli@3.4.1/src/commands/start.js:188:43)

I went and did expo init on a new project, and same exact error.

Also ran these commends:

npm uni --no-save @expo/xdl
npm i --no-save @expo/xdl@56.8.0

Same error.

Hi buddy, just trying string in the next line and see if that works.
