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

Extension Pack for Java、Language Support for Java(TM) by Red Hat、Debugger for Javaを使用して、Windows 10 Pro、JDK 17.0.6、VS Code 1.76.2、Java extension 1.16で報告された動作を再現します。importと変数のハイライトを期待されるスクリーンショットと比較し、クイックフィックスが利用可能か確認します。ハイライトとクイックフィックスの両方が期待どおりに機能すれば完了です。
