Why GGG didn't fix vulkan crash yet?

It’s been two weeks since the league started and I still can’t understand why they haven’t fixed this crash. Are there simply not enough players using Vulkan to justify a fix? I’m honestly burned out from playing the content at 10 fps on DX12. Are they unaware of the issue or just ignoring it? How can we, as players, actually get the tech team to address and resolve this problem?
