TypeError on Lutris startup, causing immediate crash

Hi, first time poster.

I’m attempting to run Lutris on OpenSUSE Tumbleweed but it is crashing on launch.

lutris --submit-issue output is here

lutris -d output is here

I am on a Dell XPS 15 9570. I have the Nvidia drivers (435) installed and working (and activated via prime). Vulkan is supported. I have the latest wine libraries installed without issue. DXVK is installed also without any issue.

If anything further is required just let me know.
