Kenshi install hangs on winetricks

When I try to install the GOG version of Kenshi, the install hangs indefinitely with this in the console output.

lutris-wrapper: /home/aidan/.local/share/lutris/runtime/winetricks/winetricks
Started initial process 135 from /home/aidan/.local/share/lutris/runtime/winetricks/winetricks --unattended dxvk corefonts ogg physx vcrun6sp6 vcrun2010

I can access the winetricks github repository from my web browser, so it does not appear to be a network issue. What else could be going on?
