This has been a problem for a coupla months. I miss my game. ;-(

One day. Valheim just wouldn't launch. I hit "play", it does the "Vulkan shaders" prep thing, and then goes right back to showing the "play" button like nothing ever happened. When I try to use different compatibilities it either does this, or appears to launch (as in the "play" button turns to "stop") but doesn't do anything else.

I'm running Ubuntu 18.04.
