Hi

That’s weird. Do you see any logs in the terminal window where you ran expo start?

I don’t know, what is the problem?
But It has already fixed.
I delete yarn.lock file, then I run yarn install.
It runs perfectly.
I suspect this is because I upgraded to the latest version of the yarn. then the device log does not appear.
