What happened?

bunx biome check . --reporter=json-pretty

{
	"severity": "error",
	"message": "The imports and exports are not sorted.",
	"category": "assist/source/organizeImports",
	"location": {
		"path": "typescript\src\account\setup-passkey.tsx",
		"start": { "line": 1, "column": 1 },
		"end": { "line": 6, "column": 26 }
	},
	"advices": []
},

The path uses unescaped backslashes, which makes the JSON invalid.

Expected result

{
	"severity": "error",
	"message": "The imports and exports are not sorted.",
	"category": "assist/source/organizeImports",
	"location": {
		"path": "typescript/src/account/setup-passkey.tsx",
		"start": { "line": 1, "column": 1 },
		"end": { "line": 6, "column": 26 }
	},
	"advices": []
},

or

{
	"severity": "error",
	"message": "The imports and exports are not sorted.",
	"category": "assist/source/organizeImports",
	"location": {
		"path": "typescript\\src\\account\\setup-passkey.tsx",
