Hello, I’ve been having this problem since 4.17 where my packaged game intermittently crashes because of failing "ensure"s but I have no idea how to debug this and if this is bug with the engine: Log file open, 02/04/18 22:19:46 LogWindows: Failed to load 'aqProf.dll' (GetLastError=126) LogWindows…

Looks like you are running a for loop on an array and changing the size of the array within the loop itself. That causes an error because the for loop doesn’t know anymore how many elements it has to loop over.
