This should be fixed now.

Are you running Wayland or X11?

Are you running Wayland or X11?

echo $XDG_SESSION_TYPE
x11

[LupertEverett]

This happens because of some recent changes. We don't have Vulkan surface creation implemented in X11/Wayland backends yet.

In the meantime, SDL2 backend might work, does the game run when you start it with the command given below?

Yep, after this commit 7689c48, the game started to run. Thanks!
