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

The issue names no source files, tests, or entry points. Start by reproducing the failure in the affected workspace, compare it with the working project, and inspect the Java formatter configuration and extension environment; done means Java files format successfully in the affected workspace.
