Standalone mode not opening

When I open standalone mode to play my game, the standalone window opens, but is black, then it crashes and I get this report:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000000000001bb

Any ideas how to fix this?

Hey @Sora2478!

To get things started, have you tried verifying your installation of Unreal? Additionally, could you make sure you have editor symbols for debugging installed so we can get a better idea of what is happening?
