[mattbrictson]

stylelint crashes with the introduction of with stylelint-prettier 4.0.1. The crash goes away if a .prettierrc.js file is created.

What version of stylelint, prettier and stylelint-prettier are you using?

prettier@3.0.0
stylelint-prettier@4.0.1

Please paste any applicable config files that you're using (e.g. .prettierrc or .stylelintrc files)

Thanks for the report. I've shipped the fix in 4.0.2.
