How can I salvage a project that now crashes on opening?

Development Programming & Scripting
1

I am not using perforce (yet, unfortunately) and my last ‘backup’ is about a week old and is missing a significant amount of work.

After the latest launcher update, my project refuses to load.
I am able to get the project to load if I delete the map designated to load by the editor but then just crash again when attempting to load a diff map (any map).

Any possible way I can salvage ANY of my project?
If not, this will be the THIRD time I have had to start over, wtf am I doing wrong?
(Pure blueprints, I am not doing ‘code’)

Update: I am attempting to get access and think i have tracked down the problem to my player controller, that is the only element shared across all the ‘maps’. The latest additions to the project were purely UI elements, I was ready to share a demo and was doing usability cleanup.

Here is the crash report I get when attempting to load my project:

Unknown exception - code 00000001 (first/second chance not available)

I’m not sure about the error or why its crashing. But since you say you can get it to load by deleting the startup map, you can also probably just edit the startup ini files in the project to not load any map and I think it loads an untitled one by default.

Might take a bit of work but:
Create a fresh project with no starter content. Call it whatever

Once in your original project:
Start from the top and right click on each map and migrate it to the fresh project.

Verfiy each map loads on the fresh project. Then do the same for your char blue prints, animation blue prints and any other blue prints.

All assets tied to the blue prints and the maps will be carried over automatically.

This will only carry over used assets so it cleans up the project and maybe you can track down what part is causing the issue by trying out the new project as you move things over each time.

the editor crashes 4-5 times a day for me. I’ve gotten used to it. Save manually often and never use the restore feature… the restore always sets me back hours. Sometimes it restores things i didnt work on that day to a state previous to where it was currently.

I’ve had crashes where the player controller was the offending asset quite often. More often than not the source of the problem was event dispatchers in the controller. Could have been luck, but in my case re routing dispatchers elsewhere created a lot more stability.

Hi ArsDigita,

If you could, upload the crash logs you get here. They are located at \Unreal Projects\PROJECTNAME\saved\logs. Additionally, if you go to the filepath \Unreal Projects\PROJECTNAME\content\ and pull out your player controller .uasset, then attempt to open the project, does the project open? If not, try pulling out the entire blueprints folder and opening. Do this with assets until the project opens. You can whittle down which asset is the problem by adding assets back in. When the project crashes, that asset or one that links to it is most likely the problem.

There are several known crashes with Event Dispatchers, how are you calling them and what was the most recent actions you took before the editor began crashing? I can find out which error you are getting and get that bug report updated with the information present.
