Hey,
Ok i’m no expert in debugging, but I had a quick look at the logs and there’s a bunch of errors at the end, especially this one that caught my attention :
[2017.08.22-15.20.58:185][706]LogOutputDevice: Error: Cannot remove redirection from /Game/Assets/Meshes/Tech/ComputerMonitors/MonitorVideo.Default__MonitorVideo_C, it was not registered
From what you mentioned, you renamed a folder and I know UE4 can go weird if it can’t find folder names or assets. I have had issues where I couldn’t package because I renamed something in the editor folders.
Anyway I’m not assuming this would cause the F11 crash, but it would certainly help.
I would also try to reinstall your GPU drivers via DisplayDriverUninstaller and perform a clean reinstall and update to the latest drivers.
Try also verifying your UE4 disk cache via the launcher to fix any missing files.
Hope it helps !
