Fixer stop working

[archergod]

I am not able to use it as it is not fixing anything. Using Developer Tool in VSCode I see this error:

[Extension Host] SyntaxError: Unexpected token 'A', "[AB00:9984]"... is not valid JSON
    at JSON.parse (<anonymous>)
    at c:\Users\Sumit Gupta\.vscode\extensions\junstyle.php-cs-fixer-0.3.18\index.js:76:39831
    at processTicksAndRejections (node:internal/process/task_queues:95:5)

I try to uninstall and reinstall but nothing fix it.
