Why doesn't expo work after the eject command?

Question

React Native

Good afternoon!
Initialized the command expo eject, chose the 2nd item

ExpoKit: I'll create or log in with an Expo account to use React Native and th
e Expo SDK.

After launch, the application appears in the list of Expo applications, but when clicked, it does not open.
Why is that?
ps than the first point differs from the second?

React Native: I'd like a regular React Native project. (See warnings above.)
