While build app I get: "Fatal error: Cannot find the keyWindow"

After building an app in Xcode (I use expo and react native) I got error: EXDevLauncher/ExpoDevLauncherAppDelegateSubscriber.swift:8: Fatal error: Cannot find the keyWindow. Make sure to call window.makeKeyAndVisible(). I have never got it before. It appeard first time after I had upgraded expo and react versions.

Since this is in a file from Expo, and you recently upgraded their software, you should get it touch with their support for how to resolve this.
