The project suddenly crashes

I was managing some stuff in UMG blueprint. Mainly changing some branches and foreachloop nodes. As far as I know I didn’t do anything that might cause error. Didn’t change any project settings or editor preference either.
Anyway, the editor got kinda slow, which tends to happen when I work for a few consecutive hours, so I compiled, saved all, and closed the project.
And then I tried to load the same project, but it suddenly crashes as soon as it finishes loading.
I absolutely have no idea why this is happening and there’s no backup files, so basically I’m about to freak out.

If someone knows what’s going on, PLEASE tell me.

Below is the log.

Hello netcop0207,

If you know what particular asset you were working with last, I would suggest navigating to your content folder and moving it from that directory manually to see if the logic changed inside of is what is causing the issue. It’s possible that you may of created an infinite loop of some sort.

As it doesn’t seem to be coming up in the log, could you post the crash report that appears when the crash happens? Copy/pasting would be best since I’ll likely need to use some of the contents to search for the crash.

I’m glad to hear you were able to salvage the project at least. If you ever run into a similar issue, please feel free to post here and I’ll look into what’s going on. It would be a good idea to try to fix the problem rather than just migrating to a new project if at all possible. In the meantime, I’ll this as the accepted answer.

Hi. Thanks for the comment, but I figured it out. After 13 long hours of banging my head against the wall. Not that I fixed it, though. It was UserDefinedStructure. For some reason I don’t quite understand, structures got corrupted and have been causing the project to crash. Right now I don’t see a good way to salvage the corrupt project, so basically I copied the whole contents of the project to a new project, deleted the structures, and cleaned up dead classes, bad structures, etc.
