Debuggung not working, VSCode 1.49.2 Espressif Extension 0.5.1

[ennogrue]

On a fresh Windows 10 2004 I installed VSCode 1.49.2 with Espressif Extension 0.5.1., plain successful onboarding.
I am using ESP Wrover Kit 4.1.
With the blink example I can build and flash the target, the console output of the blink application is fine.
But I cannot debug:
F5 doesn't work.
When starting the openocd server I get:

What does the error "type 'esp32' is missing virt2phys" mean and how can I avoid it?

My settings.json:
{
"C_Cpp.clang_format_style": "Visual Studio",
"editor.formatOnSave": false,
"[cpp]": {
"editor.quickSuggestions": true
},
"[c]": {
"editor.quickSuggestions": true
},
"C_Cpp.intelliSenseEngineFallback": "Enabled",
"idf.adapterTargetName": "esp32",
"idf.openOcdConfigs": [

"board/esp32-wrover.cfg"
],
"idf.portWin": "COM7",
"idf.toolsPathWin": "C:\\Users\\eg\\.espressif"
}

How can I make debugging work?
