I was able to reproduce this issue @g10. After some digging, I found that Next added tracing (collecting performance metrics) to many of it’s internal Webpack plugins in 11.1.1. This is a breaking change since for us since we use their default webpack config and don’t specify a trace. The fix should be pretty straight-forward but Next currently doesn’t export any of the tracing code so I’ll followup with the Next team to see if they can export what we need.

Edit: Nvm I found the deep export I was looking for. I have a PR to fix this here https://github.com/cypress-io/cypress/pull/18189
