Using UE 5.5.4 I’ve been spending 4 days trying to solve this issue and unfortunately it’s still not working. Either Blueprint or C++ MVVM, either manual / create instance / global collection even resolver (also Blueprint and C++) I’ve tried everything but it doesn’t work, I will get this error.
The base layout I’m using is a widget with a MVVM inside a root widget, the root widget is soft referenced in the HUD class, and thought that the cause was the root widget having a hard reference to the child widget. So instead I put the MVVM inside the root to control the child widget, so that the actual widget using the MVVM was soft referenced for sure. Guess what ? Still not working.
Also tried deleting Binaries, Intermediate, Saved files of the project, deleting the AppData/Local/Unreal/5.5 and /Common caches, still no result. Did a test project to see if something was not corrupted, still no result, it doesn’t make sense.
The HUD is created in the a GM C++ class using the FClassFinder.
I’m giving up on this, if anyone find a real solution or explanation, or just fix this, it would be great.
