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

使用 Extension Pack for Java、Language Support for Java(TM) by Red Hat 和 Debugger for Java，在 Windows 10 Pro、JDK 17.0.6、VS Code 1.76.2 和 Java extension 1.16 上重现报告的行为。将 import 和变量的高亮显示与预期的屏幕截图进行比较，并验证是否有可用的快速修复。高亮显示和快速修复都按预期工作即表示完成。
