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

Riprodurre il comportamento segnalato con Windows 10 Pro, JDK 17.0.6, VS Code 1.76.2 e Java extension 1.16, usando Extension Pack for Java, Language Support for Java(TM) by Red Hat e Debugger for Java. Confrontare l'evidenziazione di import e variabili con gli screenshot previsti e verificare se sono disponibili correzioni rapide. Il lavoro è terminato quando sia l'evidenziazione sia le correzioni rapide funzionano come previsto.
