Originally the game would crash at the "Planet Generation" screen at 0 complete. After trying a bunch of stuff, adding the VK_ICD_FILENAMES and VK_LAYER_PATH to the launch options fixed the issue. I had to change my VK_ICD_FILENAMES variable, by using the command "ls /usr/share/vulkan/icd.d/" and then using one of the files in there as my VK_ICD_FILENAMES variable. The other fixed using VK_ICD_FILENAMES didn't have the same file names as my system.

Launch options "VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/amd_pro_icd64.json VK_LAYER_PATH=/usr/share/vulkan/explicit_layer.d %command%" is probably all you'll need to get past the planet generation screen.
