Stuck in Importing

Hi, I was trying to make JUnit work so I made co-pilot do a few things but I couldn't follow it as it had done a lot of things. Now neither my program nor VS Code works (at least while trying to run my program).

Stuck in "activating task providers java"

Java: Clean Java Language Server Workspace does not work (command not found)

When I click "run Java", this thing on bottom right appears but nothing happens (waited 3+ minutes, my program used to run in less than 5 seconds after pressing run)

Nothing of significance in "Problems"

This guy at the bottom is probably related to the main cause of the issue but disabling it and restarting VSCode etc does not change anything. The same issues still persist. (Command not found, activating task providers java, run importing projects etc all the same). I disabled it for now.

Extension Host

Window

Not sure if relevant, but Java: Configure Java Runtime leads here although I am in a file as you can see on the left (but I'm not sure what this is so this information is probably irrelevant and makes me look stupid as it is also incorrect lol)

I have been trying to find a solution both with internet searches and AI suggestions for a few hours now but couldn't find a solution. Please help! I wish I just did not try to "force" the optional part of my homework; I was done with it and now it doesn't work and I need to show it to my prof in a few hours :D

I'm using Windows 11, this additional info may help link here

首先查看链接的 vscode-java-test 评论以及报告的 Windows 11 症状：“activating task providers java”、缺少“Java: Clean Java Language Server Workspace”命令，以及项目导入停滞。重现该故障，并检查屏幕截图中显示的 extension host 和窗口信息；完成的标准是确定原因，并恢复 Java 项目的导入和运行行为。
