Answer 1

Worked around by deleting .next folder and running yarn run dev again.

Answer 2

As stated in this discussion, the suitable solution in your case seems to be:

cd [your project]
npm install -g n
sudo n stable
rm -rf node_modules/
rm -f package-lock.json
npm install

I really can't reproduce the error so I'm not 100% confident this is going to work but you can give it a try and let us know. I also think you can skip the installation of a stable node version so, if you already have one, just try the clean npm install.
