in my case, npm cache verify helped to solve this problem (win10, vs code)

Stop the project and try running npm cache clean. If that doesn't work, try npm cache clean --force.

Navigate to the mentioned directory (C:\Users[username].expo). find state.json. duplicate it (state Copy.json) and remove the previous version. make sure the file name is state.json and voila.

try running npx expo login again.
