Usually when I run npm start
/ expo start
the expo CLI starts and I am able to scan the QR code using expo on my phone. However after I start the app a few times, the QR code no longer begins to show up and I can no longer scan it.
Bottom Lower Corner of the Expo Developer Tools which usually shows a QR code
NPM command prompt running without a QR code

For me, I also had an error at the top of the console:
Linking is disabled because the client scheme cannot be resolved
To resolve, I simply had to run this:
npx uri-scheme add [your app name]
It added the uri schemes and the app then showed the QR code.

I have faced the same issue when I updated the expo-cli with this command.
npm install -g expo-cli
I have followed these steps and worked for me,
CTRL+C
node_modules
folder in the projectnpm install
npm start
I hope this would help you.
