I only added the bit about winetricks after reading your comment. And the bit about wine was only added recently too - so might not have been there when you looked.
I've never owned a Radeon card before - so I can't help in terms of driver support. But I do know you can launch the game without Vulkan (and use OpenGL instead). In user_settings.py (which will be where you extracted the custom Proton), find the following lines:
Code:
#Use gl-based wined3d for d3d11 and d3d10 instead of vulkan-based dxvk
# "PROTON_USE_WINED3D": "1",
and uncomment the PROTON_USE_WINED3D line. It should result in the use of the built-in Wine libraries which provide OpenGL support.
Edit: I forgot to mention that I couldn't see anything in your logs. It looks like the ED client might have frozen as what was in the log seems to all be from the Launcher. If you grep your log for VK - this will show most (all?) of the DXVK entries. When I ran in to problems with Vulkan - it had a message about required Vulkan extensions not being supported. I think it was: "Required Vulkan extension VK_KHR_xcb_surface not supported"
