Exiting because of an error: could not determine Python version: exit status 103

[JoshuaCousins]

Which tool versions are you using?

SDK: v14.8.0
Platform: v0.33.5
Python: v3.9.13
Isolation mode: venv

Current Behavior

When Running the command viktor-cli install I get the error:
Exiting because of an error: could not determine Python version: exit status 103
despite the fact that python 3.9 is correctly installed and my path is correctly set up - running python app.py produces missing module error, but still runs the code.

Expected Behavior

The app installs correctly and I can resume work on the project

Context (optional, but preferred)

I saw a related issue where the problem was solved by reinstalling python not from the Microsoft store, but from the official installer - I tried that but it didn’t work, tried resetting the PC completely and reinstalling Windows, also didn’t work. I have attached screenshots for clarity - please let me know if there is more info needed! Thank you <3

Could you try running viktor-cli check-system and see what the result is?

Hi Daniel, here is the result:

[Daniel]

could you show me what the viktor.config.toml looks like?

[JoshuaCousins]

viktor.config.toml:

# For all available configuration settings, please go to:
#   https://docs.viktor.ai/docs/create-apps/references/viktor-config-toml

app_type = 'editor'
# assets_path = 'assets'
# packages = []
python_version = '3.9'  # '3.9' | '3.10' | '3.11' | '3.12.2'
# welcome_text = 'welcome.md'

When I try to run viktor-cli start, I get the error:
Exiting because of an error: app is not (properly) installed

Hi Joshua, could you try to manually remove the venv directory that is present and reinstall the app?

[JoshuaCousins]

That fixed the issue, thank you so much!
