Java Project in VS-Code, "No delegateCommandHandler for vscode.java.validateLaunchConfig" Error

Question

I'm new to Java in Visual Studio Code and trying to implement small application, which is using our SDK, which is located in our internal Git Repository.

When trying to Debug my application I get following Error:

No delegateCommandHandler for vscode.java.validateLaunchConfig

My Configurationfile looks pretty simple:

{
    "configurations": [

        {
            "type": "java",
            "name": "CodeLens (Launch) - App",
            "request": "launch",
            "mainClass": "com.my.first.class",
            "projectName": "dummyproject"
        }
    ]
}

I'm using following Extensions for Visual Studio Code:

• Debugger for Java (0.20.0)
• Gitlens (9.9.0)
• Java Dependency Viewer (0.5.1)
• Java Test Runner (0.18.1)
• Maven for Java (0.18.1)
• Java Extension Pack (0.7.1)
• Language Support for Java (0.47.0)
• Visual Studio IntelliCode (1.1.8)
