Oversteer won't launch on Arch Linux

[lexd0g]

Installed both from AUR and tried compiling/installing manually. Running Python 3.10.1. Here's the error I get when trying to launch, happens both when trying to launch the GUI and trying to run any CLI commands. Also tried installing new-lg4ff.

You should use a locale with UTF-8 support. Is there some reason to use something different?

[lexd0g]

I do have UTF-8 locales installed. en_GB.UTF-8, en_US.UTF-8 and es_ES.UTF-8.

Which one are you using? Please, paste the output of locale command.
