Why am I unable to launch any games?

When I try to launch any game (in this case a blank one), I get this log output:

LogPlayLevel: Program.Main: ERROR: AutomationTool terminated with exception: AutomationTool.AutomationException: Failed to copy C:\Program Files (x86)\Epic Games\4.11\Engine\Binaries\Win64\UE4Game.pdb to C:\Users\Nathaniel Warner\Documents\Unreal Projects\LevelDesignProject\Saved\StagedBuilds\WindowsNoEditor\Engine\Binaries\Win64\UE4Game.pdb

I don’t know why this is happening because I have not done anything weird with UE4, and I’ve tried reinstalling it multiple times. I’m running Windows 10 64 bit. The file that it says it “failed to copy” (UE4Game.pdb) actually does exist. Is this a bug of some sort?

Hey Nathaniel515,

Please open up the Epic Games Launcher and then go to Library > click on the down-ward arrow beside your engine version > Options > place a checkmark beside Editor symbols for debugging.

Once that’s installed, this error should clear up. Thanks!

Thanks! Didn’t realize I needed those editor symbols (they’re a large download)
