What graphics card are you using? I've heard of this happening because of graphics card issues with the new OpenGL standards Blender uses in 2.8. You can try starting it with --debug-gpu command flag and see if that will launch it. In the meantime, make sure your graphics card drivers are updated to support at least OGL 3.3, which is the minimum requirement for Blender 2.8. Aside from some debug trickery on startup, I have not seen an actual fix for this issue, which some people seem to be experiencing, outside of simply waiting for the full release and all the bug fixes.
