Crash Ensure condition failed: !UberGraphFramePointerProperty == !UberGraphFunction BlueprintGeneratedClass.cpp Line: 1357

Hello,

My project is a blueprints one. Code is only in plugins. I’m using UE5.03.
Some days ago, a structure got corrupted. I had to delete the variables using it, delete it, recreate it, add the variables and fix the logic. Everything was fine when I closed the project. But when I opened it again, something happened… but I don’t know what. I mean, now if I try to open a blueprint (any), it crashes with this error :

I tried replacing some blueprints with ones from a backup, nothing changed. :sob:

I disabled the plugins and now the error is :

Assertion failed: FieldClassPtr [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\Field.cpp] [Line: 983] Field type UberGraphFrame does not exist

I asked the launcher to “verify” UE5.0.3. Nothing changed.

This is hell… does anyone have a idea ? Thanks a lot !

Did you find a solution? I have same issue, cause by a corrupted structure too

I migrated the whole project. I had to set the preferences again, some config files, manually copy a ton of files cause the migration su**s… And it worked. After losing some days…
Also, looks like I had a plugin corruption prior to all of this so I reinstalled it.
I love this :crazy_face:

The logs for this problem are useless, having to recreate the project is a huge pain and this is the main reason some devs don’t want to touch unreal. I guess with time they could fix it, but I don’t count on it. I’ve been trying to debug this and the trails ends here. I think I’m done.

Sorry if i unearth this thread, but i had exactly the same issue and that even totally sudden, but i found out why it happened and how i fixed it. So maybe this helps somebody else.

However it was even weirder for me. So i mainly develop on mac and on there the game was building properly. However when i synced everything to my windows machine, for windows test builds, the build process failed with exactly the same errors. Even though just 2 days before it was building just fine.

After lots of trial and error, i found the issue. On my mac while it compiled and built fine, it always threw 2 warnings, about the Linker using placeholder data in a struct in a gamestate object and a gameinstance object. However building the game ran fine as said.

So after i had these weird errors, i further checked the warnings. Turns out, in both of the objects i had a struct where i temporaly changed the default values some time ago for testing. In there i was referencing a class to spawn further down the line.

However the class the struct was referencing by default was not there anymore but i had moved it in a subfolder to make things a bit more structured. While it did updated the reference in the actual structs default values, it apparently did not update the changed default value in the struct in the gamestate / gameinstance.

From my understanding unreal still has a little failsafe where it places a “link” from the old files location which points to the new files location. I assume this is why i only got the linker warning on the mac, since it was still able to resolve the changed class location.

However when syncing the files to my windows machine, apparently this “link” is not synced as well, causing the build process trying to access a class (in my case) which simply does not exist anymore which apparently hard crashes the compiler.

I fixed it by simply removing the temporary default value in the gameinstance / gamestate and recompiling the BPs and tada: It worked just fine. Even when completely removing the folder and syncing it again, it builds without any errors or warnings now.

So while i cannot give a 100% guaranteed solution to this issue, i can give at least a hint: If you have moved an asset and suddenly get this error, try to check all BPs referencing the asset if the issue could be there, in the variables / default values of structs etc.

However it still would be nice if the hard crash would give a little more information, at least on which BP it happened.

But yes, i hope it helps somebody sometime :slight_smile:
