Help with Crash, trying to launch project on windows.

Does anyone know how to stop unreal from crashing and actually get it to package a project for once?
When i try to launch my project Unreal crashes and i get this log.

Thats why. The only thing i can think of would be to try and turn of “Use Pak File” in the Project Settings>Packaging

Could you submit a bug report to see if that is supposed to be limited to 2GiB?

I knew someone would assume it was the 2gb limit, thanks for your input thought i know you’re well meaning. I will try the turn off pack file tip thanks.
My current project is not so large, and i have actually packaged it before. If anything changed apart from updating to the 2nd preview of 4.11 then it can only be that i may have changed a texture or the FPS blueprint in some way.
I submitted a report, and posted on answer hub, it was removed from answer hub - i also searched answer hub for those who had similar problems. It turned up a mixture of threads that were either left unanswered or the user solved themselves, non of which helped rectify my situation.

But you should not use a preview release for “Mission Critical” work/projects, It tends to happen that using beta’s/previews/Etc have problems that may cause unforseen issues and what not.

It’s just that I’ve seen a couple people complain about how this or that preview has broken this or that and they are unable to continue.
