I ran into this problem today when updating all our dependencies.
We configure webpack ourselves and aren't running a vanilla Create-React-App setup so our environments are different to yours.
For what it's worth...
I installed the dependency and tried turning it off an on again, seemed to do the trick.
Explicitly declare the #babel/runtime in package.json file
"devDependencies": {
....other dependencies,
"#babel/runtime": "^7.15.4",
}
Delete the package-lock.json file
Re-install dependencies
npm install
Error went away, your set up might be different with create-react-app so I hope this works for you too!
