Language Support for Java(TM) by Red Hat not working properly

When using the VS Code and the usual Java Extensions (Extension Pack for Java, Language Support(Red Hat), Debugger for Java) the color highlighting of the imports and some variables is kinda odd. In addition to that quick fixes are no longer availible.

This whole setup was working just fine until monday (20.3). This is a company computer so I dont what caused this error.

I've tried to reinstall VS Code aswell as all the extensions and it still appears in older VS Code Versions (1.70.2) and extension versions (down to 1.13).
Sorry if this problem was already mentioned and I was unable to finde the issue and solution for this.

Environment

• Operating System: Windows 10 Pro
• JDK version: 17.0.6
• Visual Studio Code version: 1.76.2
• Java extension version: 1.16

Current Result

Expected Result

Reproduisez le comportement signalé avec Windows 10 Pro, JDK 17.0.6, VS Code 1.76.2 et Java extension 1.16, en utilisant Extension Pack for Java, Language Support for Java(TM) by Red Hat et Debugger for Java. Comparez la mise en évidence des imports et des variables avec les captures d’écran attendues et vérifiez si des corrections rapides sont disponibles. Le travail est terminé lorsque la mise en évidence et les corrections rapides fonctionnent comme prévu.
