The warning: PIE: Warning: AttachTo: ‘/Engine/Transient.World_2:PersistentLevel.BP_FirstPersonCharacter_C_0.CollisionCylinder’ is not static (in blueprint “BP_FirstPersonCharacter”), cannot attach ‘/Engine/Transient.World_2:PersistentLevel.BP_FirstPersonCharacter_C_0.FirstPersonCamera’ which is static to it. Aborting.
I also did a construction script tutorial I found but that didn’t work (picture01)
It looks like error has to do with your First Person Camera, not the capsule component. Try going through each component in the Components window on the top left and manually set their mobilities to Moveable in the Details panel. You should be able to see exactly what nodes are causing the problem by double-clicking the warning/error.
