4.11 Preview 6 Crash renaming blueprints

The editor crashes every time I try to rename blueprints in the content browser. I choose rename from the right click menu or click twice on the asset name and once I hit enter with the new name, some quick progress bars appear (can’t see what they are), then a request to check out the asset pops up. Upon selecting to check out from P4, the editor crashes.

The crash logs don’t seem to provide any help as they just show Perforce trying to rename and then the last line says the file with the new name doesn’t exist. P4 does check out the file, but makes no changes to it. I can revert unchanged files and it always reverts.

I’ve looked through lots of forum posts and searched through AH posts for solutions, but nothing has worked so far. I even went as far as rebuilding my player character from scratch and removing all references to the old one since it was the first place I saw this issue and most blueprints are connected to the player in some way. This didn’t fix anything.

I’ve tried making the name change on a copy of the project outside of source control hoping it was a P4 issue, but that didn’t help anything. This project is a new blank project that I migrated my maps to as a way of removing unused assets more easily. I copy/pasted some stuff from .ini files to get input set up correctly again. Could that be an issue? The game works perfectly fine and can be packaged with no issues either.

I’m at a complete loss what to do here. Epic has requested my files to review for the Marketplace submission, but I can’t get the files renamed the way they want them for submissions. Does anyone have suggestions where to start to solve this?

I’ve attached a sample output log from after the crash.

Hey Gooner44-

I tried checking out an asset when prompted after renaming it and was able to do so without crashing. Can you post the callstack from the crash as well. Does this crash occur if you rename a newly created blueprint as well? Were you doing anything else with the project when renaming the blueprint (saving/syncing to/from Perforce/etc)? let me know of any other information you think may help me reproduce this on my machine.

Cheers

I’m not doing anything else when I try to rename it. I’m guessing it’s a reference to a bad/corrupted ‘something’ since I can rename new assets and some of the existing assets I have. I suspected maybe some sort of circular reference based on what I’ve , but I guess that’s supposed to be fixed? I can’t attach the files that are in the AppCrash folder linked in the Crash Reporter, the .dmp file is not a valid file type. The only thing in the bottom box is this:

MachineId:88EA2A25417775EE9A5C2F920A1CCBC0
EpicAccountId:ae393a9505e24920af14eef5b3785f1f

You do not have any debugging symbols required to display the callstack for this crash.

Can I get symbols for the launcher downloaded Preview 6 build somewhere? I’m a Blueprint only person, but do have VS so maybe with symbols (and some instructions on where to put them) I could see at least what’s causing this if not fix it on my end in BP?

Here’s a callstack from one of the renaming tries. Interesting note that I put in one of my crash logs sent to Epic… The same crash (or at least the break point at the same place) happens by just moving nodes in blueprint and compiling. No connection or disconnection of lines, just move/arrange nodes and compile. 100% crash from what I can tell. Maybe that’s an easier repro on your side?

One other thing to note. This project I’m working on has been converted from one version of the engine to the next since around 4.1 with maybe a version or two missing somewhere in the middle. Maybe some legacy stuff is stuck in there? Callstack

Alrighty then… here’s some fun info to go figure out.

Due to the bug I mentioned above regarding moving nodes, but not connecting/disconnecting pins, my workaround when cleaning up a graph was to always disconnect and reconnect some execution pin then compile/save. As I was explaining that to a friend who was looking into the rename issue for me, it hit me, why not try the same thing since it’s the same crash. Guess what, I can rename fine now.

So, repro is simple. Rename a blueprint or rearrange the nodes inside it without messing with pins, compiling will crash. Disconnect a pin, then reconnect it and rename, compiling will go fine. Fix up redirectors and all is right with the world. Would be nice to know what that’s all about, but at least I can move on with my work.

I tried testing further but have not seen any crash when renaming blueprints. Are you able to reproduce the crash in a new project with no additional content? If so can you list the steps taken that cause the crash? If you are unable to reproduce the crash then it may be project specific. If you could zip your project and post here; or you can post it to google drive / Dropbox and send me a PM on the forums with a download link for privacy.

In a new blank project I’m not seeing this. I’m consistently getting the crash when moving nodes in my project though. By unhooking and re-hooking a wire I was able to rename everything as needed. I’ll pack up the project and send you a PM so you can look at it. Maybe it is some really old stuff lingering. Would be good to have someone that knows what they are doing debug this. :slight_smile:

Hey Grooner44-

I saw the project that you sent me via PM, however the file size is too large. Could you remove the Saved and Intermediate folders from the project and zip it again to reduce the size of the folder. Let me know when you’re able to do this and readd the proejct to dropbox and I can take a look at it.

Hi Grooner44,
