Proton also depends on DXVK, an additional translation layer that specifically bridges the Windows graphics APIs to Vulkan (as opposed to WINE handling its system calls in a general sense). Meanwhile, newer versions of macOS (and the M1 that runs the ARM builds in particular) don't use Vulkan at all, opting for Metal instead.
