Java Formatter is broken somehow in my workspace

So I played around trying to use a custom formatter for Java. At some point my workspace broke and now I cannot format any Java code.
I tried to remove every setting related to formatting. I used "clean the Java language server workspace"
I deleted workspace caches in %userprofile%\AppData\Roaming\Code

Nothing works. Now I get the window "There is no formatter for Java installed" whenever I try to format some Java file.

I tried to set up a formater again. I added the file, used these settings:
"java.format.settings.url": ".vscode/GoogleStyle.xml",
And now I can run "Open Java Formatter Setting Wth Preview ", but I still cannot format my code.

Also I created another small project with one Java file and there the formatter works.

Environment

• Operating System: Windows 11
• JDK version: 11 and 17
• Visual Studio Code version: 1.71.2
• Java extension version: 1.11.0

この issue にはソースファイル、テスト、エントリーポイントが記載されていません。まず影響を受けている workspace で失敗を再現し、動作しているプロジェクトと比較して、Java formatter の設定と拡張機能の環境を調べてください。影響を受けている workspace で Java ファイルが正常にフォーマットされれば完了です。
