I cannot save the created BP_SecretWall created using the Blueprint button as shown below.
It ended with error message below:
Later, I found a related thread HERE from other student, the method using Content Browser, Add > Blueprint Class, then search for StaticMeshActor works for me.
I believed this is a UE5 Bug and already submitted this problem to UE.
After two days, somehow this issues is resolved using the Blueprint button method, I am unsure why, but considered this as intermittent problem.
You can always report UE Bug HERE.
Hopes, this help.
