I know it's already been a month but in case you still need it or someone else has the same issue, I got the same error message and was able to solve it with the solution provided on this post.

Apparently it has something to do with the "react" and "react-dom" versions not being the same. And running the following command on the terminal fixes it: npm rm react react-dom && npm i -s react react-dom
