When I try to modify a Blueprint structure, the Editor crashed and show the following report:
Assertion failed: ((UObject*)ContainerPtr)->IsA(GetOwner()) [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Public\UObject\UnrealType.h] [Line: 714]
‘Default__REINST_SKEL_BP_A_C_1377’ is of class ‘REINST_SKEL_BP_A_C_1377’ however property ‘COP_XXX’ belongs to class ‘SKEL_B_C’
The problem paused my work.
How can I fix this problem?
Tnks!

can you share more of the log or stack?
what’s the context of that issue?
