Hello,
It looks like Python was not detected. Did you provide the Python path in the ESP-IDF Configuration window while installing the tools?
You can try setting it manually in Preferences, then click on "Add ESP-IDF" and check if the Python path is being detected correctly.
Also, what IDE version are you using? Our latest release is v3.6.0.
