I’m having issues with part 3 of the beginner section. I’m using Unreal 5.6

In our example, the key point is that bManualAttachment needs to be false because we don’t want the spline to move together with the character . In other words, it will be part of the character but not follow it.

In the code it’s set to true.

If bManualAttachment is set to true, the Blueprint complains that the LocatorComponent hasn’t been set and doesn’t perform ShowPath

if bManualAttachment is set to false, the game and engine crashes when calling:
UNavigationPath* Path = UNavigationSystemV1::FindPathToLocationSynchronously(GetOwner(), Origin, Target);

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000000000005e1

which would suggest the same thing. I’ve followed the tutorial to the letter as far as I can tell but I feel like a step is missing somewhere.
