Closing UE4.14.3 Project Causes Windows Crash?

Hi everyone,

I have recently been encountering some sort of bug when I attempt to close my UE4.14.3 project. Once I click the close icon on the top right, Windows (10) will imediately go to the blue crash screen with the following stop code;


This has happened to me twice in the last week or so now.

The first time I had gone to file>save all, then tried to close straight after that and the crash happened. After the windows restart was complete I reloaded the project and had lost the entire level I was working on. Very frustrating.

The second time I also used file>save all, but this time I went off and used firefox for 5 min, then came back and closed the project. The crashe then happened again but thankfully no levels were lost when I reloaded the project this time.

Does anyone have any idea on why this may be happening?

Hi louiecraig,

Looking into the error above I found the following link:

How To Fix REFERENCE_BY_POINTER Blue Screen Errors (0x00000018)

Most of the causes listed would not be specific to UE4 unless there was a corruption in the Windows registry, in which case uninstalling and reinstalling UE4 may resolve the issue, if the problem only occurs when running UE4.
