Researching I found that this issue was reported before and closed in #1871, then possibly reintroduced in PR #1920 https://github.com/nrwl/nx/commit/08f3844007b0224f33b9d78b057a9176b672a0d4#diff-1fdd8c5d37dfa7a97c04b3b7e4c64fafL42 and researching the error I see many solutions pointing towards transpileOnly.

We are experiencing the same issue when running cypress in CI for our project, and were only able to resolve it by running our e2e tests in chunks, i.e. entirely isolated using a test name pattern. This seems to work fine so far, but comes with limitations (multiple test runs in cypress dashboard, decreased maintainability).

It would be amazing to see a final solution for this in the future.

Thanks for this awesome tool by the way! @FrozenPandaz

Unfortunately, we switched type checking back to being handled ts-loader instead of fork-ts-checker-plugin because it was causing cypress to hang when using a support file.

I believe this unintentional functionality but have not found a fix.

We probably need some assistance from the Cypress team to figure out what is going on here.
