Packaged Project Not Responding

When I launch my packaged project, it freezes and task manager says its not responding. It takes up 400mb of RAM and 0% CPU. This also happens when I use the visual studio debugger. My project was working fine before and It still works fine in the editor/standalone. Please help I have no idea what is happening.

Here the line thrown from the debug: Microsoft C++ exception: xSharedMemoryException at memory location 0x000000378AD7EBA0.
