'Expo start' not running app

Expo Development Tools
1

Due to the use of MapView with Google Maps Api, I had to build my app with expo build:android but after the build operation, the expo start command always return an error after some minutes, here is the error below:

Error: Failed to start watch mode.
at Timeout.setTimeout [as _onTimeout] (C:\Users\DevLewa\Documents\android\fpi-map\node_modules\jest-haste-map\build\index.js:935:24)
at ontimeout (timers.js:436:11)
at tryOnTimeout (timers.js:300:5)
at listOnTimeout (timers.js:263:5)

How do I resolve this?

Hey @lewa,

Can you run expo diagnostics and paste the log that is printed out here?

Cheers,

Does the same thing happen if you expo init a new app as a test?
