I have a project that I normally work on my desktop. However for some reason it decided to not open anymore (literally after working on it 5 hours earlier) and just crashes on startup. I copied the entire project folder to my laptop running the same unreal version and it opens just fine. Deleting the Config folder on my desktop gets the project to open however opening any blueprints causes it to crash. I’ve also tried various backups (from the project directory) and nothing seems to work. I even tried reinstalling the engine on my desktop. I’ve attached the logs of both the desktop and the laptop.
Hi ,
Can you post your dxdiags from both your desktop and laptop here? Additionally, what happens if you completely remove the project from your desktop then pull the project from your laptop to the desktop and open it again?
Thanks for the reply. I had originally deleted the project from the desktop, copied it to the laptop then back again like you mentioned and it still crashed. I did some more tinkering around with my desktop including a system restore to a few days ago. Initially it still crashed after the restore. I can remember the only thing that I did between working on it in the morning (30th) and the evening (same day) was update GeForce Experience (the app not a driver update). What I did after the restore was I deleted Unreal Tournament (free up space on that drive) as well as the editor (I was planning on wiping the drive and making a new OS install because of other problems lately) and suddenly it decided to work. I doubt it was the Unreal Tournament Install but my laptop doesnt have that installed so I’m not sure plus all development of this project started on my desktop with UT installed.
I am now getting a crash when trying to load a map however. Mind you that all the crashes I experience on my desktop do not occur on my laptop.

Does your editor crash if you start a new, blank project with no additional content or is it limited to your specific project?
It is only that specific project. New projects work fine as well as other projects. It seems like, at least for now, the only thing that causes a crash in this project is opening a specific map. All other maps work fine even ones that use similar assets, and all other assets seem to open without crashing. Remaking the map isn’t too much of a hassle, though it would be nice to get this project working properly again.
This map opens on the laptop without any crashes though? That is extremely confusing. Can you PM me a link to your project on the forums? I’ll be happy to take a look and see if it crashes on my end and what may be occurring.
Sure thing. Its a fairly large upload ~ 500mb compressed. I would also like to point out that this isn’t the first time this particular map has crashed on opening. Before I was working on this project it started with 4.6 and migrated to 4.7. This caused some issues and a complete re-write was made in 4.7 copying over what was necessary. It still doesn’t make sense why its not working on one computer. I’ll PM when the link is ready.
I have been able to reduce the scope of the problem to your Blueprint\Game folder and Blueprint\Player folder. What are the most recent changes you made that started these crashes? I can’t even open the project if either of these folders are in the blueprints folder currently.
The problem when I was debugging trying to get it to load on my desktop earlier came down to deleting the GameInstance blueprint. It eventually loaded though opening any blueprint after that resulted in a crash. Was there a specific blueprint that you found caused it for you?
Also is it giving you the same Struct property ArrayDim error? That was the error I would always get.
That is the error I was receiving. Is anything casting to the game instance or do you have any blueprints that are casting to one another? I’ve been able to open some blueprints such as those in the Environment folder, however anything in the player and game folders seem to immediately crash. I haven’t been able to narrow it down further yet but I’m still looking into it.
The level blueprints cast to game instance as well as some of the UMG widgets. I have quite a bit of casting going on. Not using pure casting if that makes a difference.
Any luck with this? I am unable to test on my end because it works for some reason.
Do you mean that it is now working on your desktop?
It started working a while ago, though you said you were unable to open the project at all. I cant test what is causing that because the project will open.
I did not. I posted a few ways up that the only thing I did before it started working again was a system restore and deleted UT and UT editor (from the launcher) The system restore didnt change any of the project files. The error that I was getting when the project wouldnt open was the StructProperty ArrayDim or something like that which I have no idea what that means.
I’ll continue looking into it on my end. This is extremely strange and I’d like to put in an accurate bug report as it is clearly crashing on my end, I just don’t know why. If I find any more information I will update here. Did you make any changes to the project before it started opening again?
Does your computer still have GeForce Experience on it or was that deleted along with UT and the UT editor? We tried this on a computer that has never had the UT editor on it but the project still crashed.
The only reason I mentioned GeForce experience was because that was the only thing that was updated between the time that I worked on it first (30th) and later that same day. You said you narrowed it down to two folders that when removed, the project would open? Do you know which blueprints inside those folders caused this? Or would it help if you could know whats inside those blueprints that may be causing this problem? Since for some reason I am able to open the project and all blueprints without problems now (on both PC’s that is).
I also kept tabs on the logs folder while launching the project. It seems like (even though it opens) it creates two .dmp files when loading the project (around 93%).
