Cannot launch GNOME Tweaks

Hello. I'm trying to launch the gnome-tweaks tool. When I click on its icon in GNOME 3, nothing happens. If I try to launch the app in terminal, it outputs the following:

Traceback (most recent call last):
  File "/usr/bin/gnome-tweaks", line 73, in <module>
    from gtweak.app import GnomeTweaks

    wrapper = metaclass(name, bases, dict_)
TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

I tried reinstalling Python, but no luck. How can I troubleshoot this?
