Built and installed it with trizen -S freecad-python3-git
on Manjaro and it works, at least the Part Design workbench.
You have probably some old version of shiboken or other packages installed. Try rebuilding and reinstalling every AUR package that freecad-python3-git depends on (recursively).

If the check fails there is little I can do about it as it most likely needs to be fixed upstream, in such cases report those upstream (maybe wait a day or two as sometimes it's quickly solved upstream) or skip the check with
makepkg --nocheck
if you don't care about the functionality that is being reported as failing in the check.
