Why won't my game launch?

I click launch and I get a crash report immediately and then it won’t even let me send a crash report.

Some of your game file data might be corrupted. Go to the EGL and open your project files, then try moving folders until it opens. This could help you figure out if just a single file is corrupt. Once I had a level that got corrupted somehow, and once I found and deleted it, the project opened.
