Please describe your issue in as much detail as possible:

Similar to #301, launching with -vulkan_disable_steam_shader_cache makes it work.

Steps for reproducing this issue:

1. Run Dota 2 using Vulkan
2. It will run but not show (no window)

Log (gets stuck here forever, seemingly):

It was working fine yesterday (though, it felt a little sluggish at times).

Same issue here. Game will not start with -vulkan without also -vulkan_disable_steam_shader_cache. It still starts fine with OpenGL.

Most likely the same issue being tracked at ValveSoftware/Dota-2#1619 and was tracked at ValveSoftware/Dota-Underlords#1.

Yes, it's the same issue and I've checked in a fix this morning. It will be fixed in the next Dota client update.
