Error on line 1

I can't tell if this is a problem with this package or stylelint itself.

I am using the standard stylelint config. No matter what I put on the first line, I am met with this same error on line 1 column 1.

According to this issue I raised in the stylelint project, updates have been made and this package needs to update to the latest version of stylelint stylelint/stylelint#5319
