hb_ft_font_get_ft_face error from CondaPkg installation

Bắt đầu với PythonPlot's src/init.jl và tái hiện lần tải đầu tiên bằng .CondaPkg/pixi.toml đã tạo. So sánh lỗi của matplotlib init.py với lỗi thư viện Qt6Base_jll xảy ra sau đó, theo dõi các phiên bản dependency và đầu ra cài đặt được hiển thị trong báo cáo. Hoàn tất khi PythonPlot tải thành công sau một lần cài đặt CondaPkg mới.

On a fresh install of julia and PythonPlot i get the following error when trying to load it:

The second time I try to use PythonPlot I get the following:

ERROR: LoadError: InitError: could not load library "/home/anton/.julia/artifacts/48d95e60ccfecd4622b42d4fbeda49b2cbc7530b/lib/libQt6DBus.so"

during initialization of module Qt6Base_jll

Which seems to be something broken in the Yggdrasil build of the Qt6Base jll package.

I haven't a clue where to even start debugging this as I am not a conda (pixi, etc) user and this seems like an issue with that side.
