Answer 1

Do an npm update @types/react. In the latest version ReactType is generic

Answer 2

I fixed this by deleting my node_modules folder and my yarn.lock file and then reinstalling modules with yarn (or npm i).

After reinstalling I had a newer version of react and @types/react, which fixes this issue.
