Have you tried to use a React component instead of the p tag?
Delete node_modules ,package-lock.json, yarn.lock, .docz from the project directory.
Then,
$ yarn install
$ yarn run dev
it's working now

@AreebSiddiqui what about npm, I have same issue, but I don't use yarn. And your trick is not work with npm, unfortunately
npm install will install dependencies from package.json whereas yarn install will prefer to use the yarn.lock file.
I think this issue is related to https://github.com/doczjs/docz/issues/1552
It seems there is a discrepancy with a package that can be fixed by adding a dev dependency.
I think @djizco is right and this issue can be closed.
