Debugging issue with ESP-Prog

In a project I’m working with for a few months now and that has always worked fine. I get an error while trying to debug with a esp-prog through the PIO debugging. The Pre build task is running smoothly. But in the Debug console I get the error " undefinedDer Befehl “platformio” ist entweder falsch geschrieben oder konnte nicht gefunden werden." which would translate to something like “undefined the command “platformio” is either written wrong or could not be found”.
I did not change anything in my build settings. The upload throuth esp-prog works fine. It’s just the debugger having an issue
platformio.ini:

;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = espidf
debug_tool = esp-prog
upload_protocol = esp-prog

When you open a PlatformIO Core CLI, does

platformio --version

work?

Does installing Shell commands make a difference?

platformio --version

gives me PlatformIO Core, version 6.1.18

the Path variable fixed it. Thanks a lot!
I still don’t understand why it worked before and now it didn’t anymore
