Game runs in Editor, crashes on startup after build. "Access Violation (0xc0000005)"

Hello, as the title states the game runs flawlessly in the Unity Editor, but crashes on startup when I try to run it after it's built. The problem only started after upgrading to Unity 5, there never was a problem when running the game when built with Unity 4. I'll post a bit of the error log and the stack trace as well. One thing I noticed that's strange in the error log is that physical memory and paging file both only have 0 MB free. Here's a bit of error.log... > space_combat_apr_19_2015.exe caused an> Access Violation (0xc0000005) in> module space_combat_apr_19_2015.exe at> 0023:014047c8.>> Error occurred at 2015-04-19_182504.> C:\Users\ASUS-tech\Dropbox\Coding\Unity\Test\Space> Combat\Builds\Apr> 19\space_combat_apr_19_2015.exe, run> by ASUS-tech. 36% memory in use. 0 MB> physical memory [0 MB free]. 0 MB> paging file [0 MB free]. 0 MB user> address space [3773 MB free].
