Crash when trying to Package Project [log included]

Hello.
There is a crash happens whne I trying to File->Package Project->Windows->Win64 [valid for today’s 4.9 master and 4.8 preview branch]

Steps to reproduce in my case were simple:

  1. Download actual sources from github (4.9 master, for example)
  2. Build engine as developer editor (just by default)
  3. Run UE4Editor.exe. Create C++ project based on top-down example (with scalable 3D/2D, no starter content).
  4. Re-start editor. Click “Build” in Editor. Everything ok.
  5. Click “Launch”. Everything ok.
  6. Click File->Package Project->Windows->Win64. Crash.

Step to solve the issue is simple too: manually delete Saved\Cooked\WindowsNoEditor folder, but first I have to close the editor. It’s not hard for me, but I find this behaviour a bit strange.

Here is the log with crash callstack at the end, may be you will find it useful and fix something before final 4.8 release: http://light-alloy.ru/ue4/crashlog1.txt

Hi Krakean,

In attempting to reproduce your crash in 4.8 Preview 2 I got a similar crash; mine occurred during the Launch On stage but was able to recover. To that end however, I believe the crash has something to do with the Launch On as I was able to recover and then package and run the exe as normal.

For reference, the JIRA number for the issue is UE-15769. I will report here with any further information. Thank you for reporting your issue!
