Describe the bug
After installing the latest version of prettier (currently: 3.9.4), running the command npx prettier . --check in the terminal produces this:
❯ npx prettier . --check
TypeError: Cannot read properties of undefined (reading '0')

Steps to reproduce
- In the blitz terminal, run
npx prettier . --check
Expected behavior
Prettier should scan and finish with the results with no problems.
Parity with Local
- I have run the project in my local machine and I could not reproduce the issue.
Screenshots
No response
Platform
- OS: macOS
- Browser: Chrome
- Version: 149.0.7827.201
Additional context
This happens with npx eslint . as well.
A temporary workaround I found is to downgrade packages to versions that don't call enableCompileCache.

This is indeed an issue. I'm releasing a fix as we speak.
