About vscode "Error: LinkageError while loading main class Main"

I'm a beginner in programming.
When I wrote the code in vscode and debugged it with F5, the following error occurred in the debug console:

Error: LinkageError loading main class

java.lang.UnsupportedClassVersionError: Preview features are not enabled for Main (class file version 56.65535).Try running with '--enable-preview'

Here's the code.

public class Main {
    public static void main(String[]args) {
      System.out.print("Hello World");
    }
}

It was done normally until just a while ago, but I suddenly put it down.
I tried reinstalling vscode and reinstalling the latest 12 JDKs, but the problem still persists.

The language is java.
The operating system is Windows 10.
JDK is 12.

I would appreciate it if you could give me an answer.
These are the images in question and launch.json images.
