Right, the Helper detected your system Python 3.14. PixelAI’s local AI server doesn’t support Python 3.14 yet because some of the libraries don’t work correctly with it.
Because Python 3.14 was found first, the Helper didn’t install use PixelAI’s bundled Python 3.12.8 runtime. I’ll release a patch shortly so this won’t happen again, the Helper will use the correct bundled Python even if another Python version is already installed.
For now, you can either wait for the patch, or uninstall, remove Python 3.14 from PATH and then run Install / Verify Python again in the Helper so it does a clean setup with Python 3.12.8.
