Can't use Vulkan?

Hello there, I think I can’t use Vulkan. I have installed Dota Underlords and got a message that says:

Failed to initialize Vulkan.
Please make sure your driver and GPU support Vulkan.

My GPU is AMD R7 240

I have installed vkmark
Here is the output that I get from the console when I type vkmark

Error: vk::Instance::enumeratePhysicalDevices: ErrorInitializationFailed

When I type vulkaninfo I get:

ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_intel.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_radeon.so: wrong ELF class: ELFCLASS32
vulkaninfo/vulkaninfo.h:477: failed with ERROR_INITIALIZATION_FAILED

Hello there, I wanted to mark this issue as solved. Here is the solution:
