Prettier for VS Code is not formatting the php code.
Any setup with Prettier and PHP plugin and any PHP file.

File should be formatted as if were using CLI.
VS Code shows message Extension 'Prettier - Code formatter' cannot format '_ide_helper.php'

It works just perfect if using CLI. Image above displays CLI charming yet VS Code failing.
That clearly suggests that the PHP plugin and the Prettier itself are fine.
Also to note, I have used for good while setup where plugin-php would be installed inside the extension's folder. That also doesn't work anymore. :(

Update: the extention works fine when using locally. It seems the issue arises when using any kind of VS-Code remote such as WSL or Docker container. The log output doesn't show anything useful. I have no idea how to debug. Only the failure message Extension 'Prettier - Code formatter' cannot format... appears at the bottom :)

Install extension v3.9.0 can solve this problem temporarily
reverting to v3.9.0 worked for my remote workspace (extn has issue with formatting html files)
