Workaround/Fix I was able to resolve this on my system via these commands:

# Create path YuzuModDownloader is checking for the .ini in
❯ mkdir -p /home/$USER/.config/yuzu/

# Sym link the actual qt-confi.ini to that location
❯ ln -s /home/$USER/.var/app/org.yuzu_emu.yuzu/config/yuzu/qt-config.ini /home/$USER/.config/yuzu/qt-config.ini

After this, the "HolographicWings" repo was able to be downloaded successfully.
