I've just got back from work after a holiday, all my work next-apps are facing the same problem.
When I run any of my next apps, I get the error advising an ) is missing in the webpack file. (Only in local dev) and I only receive a white screen.. This is the same across various next-apps
If i build and then start, I don't get this error.

Has anyone had this error before?

I've tried the following:
- Updated webpack
- Updated Node
- Updated all dependencies in my apps
- Git cloned the same repo again
- Checked env to ensure no errors
- No build errors
