Help! My Unity project does not start! I get to the splash screen, select my project, and then Unity simply does not open after that!
I have had this problem extensively (Windows 10 64bit). To fix this, unfortunately you need to restart your computer, and then start Unity again. If you still do not see your project, wait a few minutes. Sometimes it takes me 5+ minutes of waiting before my project finally shows up.
If I find a permanent fix to this issue, I will update this blog post.
