i solved by

Blockquote

Reset Content and Settings

Blockquote

in the Simulator. Similar to #67 in this regard. then later close the stimulator and terminal. to avoid future issues like

Blockquote

FetchError: network timeout for API calls

Blockquote.

Switching to Node 18.13.0, previously Node 21.5.0, and building again solved my problem.

If you are not able to boot the simulator and the option for Reset Content and Settings is greyed out, You can try this

Mac --- > System Settings --- > Storage --- > Developer --- > Delete Xcode Caches.

Restart the simulator.

Start the Simulator separately with the following command: open -a Simulator After this if you run expo start again and type i the Simulator will boot up properly.

It may be an issue with some outdated simulators in your simulator cache. On MacOS remove the sub-directories in the following directory:

~/Library/Developer/CoreSimulator/Caches/

check if you have .watchmanconfig file present in root, if not create one .watchmanconfig and initialize empty object and run command npm start again

For anyone like me also searching this issue, it is possible to un-eject your app and run again like normal. From the docs, Delete the ios and android directories from your project. Delete the isDetached and detach keys from your project's app.json. You can now use your project like a normal Expo project (with no ExpoKit). Read more at https://docs.expo.io/versions/latest/expokit/advanced-expokit-topics/

FOUNT IT!

you must have a .watchmanconfig file (like below)

File example

When you initialize a project with expo init "projectname", there is no .watchmanconfig file.

So, create one and in this file, just initialize an empty object like this : {}

Then you can start with expo start or yarn/npm start

It solved all my problem.

Hope it does for you too.

This usually is an error with the Simulator. If you remove expo (delete the app) from the simulator and run the command again, it should build fine.

However, if it still fails, Erasing all content and settings on the simulator does the trick too.
