Issue Description

I recently added a couple of ESLint rules that required me to add this to my .eslintrc.cjs config:

	"parserOptions": {
		"ecmaVersion": "latest",
		"project": "./tsconfig.json",
		"parser": "@typescript-eslint/parser"
	},

This is causing the following error in VS Code in some of my TS and JS files:

Parsing error: "parserOptions.project" has been set for @typescript-eslint/parser.
The file does not match your project config: src\router.js.
The file must be included in at least one of the projects provided.

The weird thing is I will get this error in a TS file in a dir, but not in another TS file in the same dir. If I rename the file with the error (something like file.ts -> file2.ts), the error will disappear, and it appears when I rename it back, so I assume it's some weird caching issue.

In my example repo, I'm getting the error for src/router.js but not for src/main.js.
