Can't seem to get Wwise Motion to work in Unreal 4.27.2

Question

I installed Wwise Motion as part of the Wwise plugin (2021.1.6.7774) in my Unreal 4.27.2 project and added motion rumble to some of my sounds. I can feel the rumble in Wwise but nothing in Unreal.
Documentation says that I should call:

        AkOutputSettings outputSettings("Wwise_Motion", 0);
        AK::SoundEngine::AddOutput(outputSettings);

I added these lines in the OnPossess of my player Controller but it makes my application crash when The AddOutput is called.

Exception thrown at 0x00007FF8CBCFB38D (ntdll.dll) in UE4Editor.exe: 0xC0000005: Access violation writing location 0x0000000000000308.

Callstack:
     ntdll.dll!00007ff8cbcfb38d()    Unknown

So my question is, how is one supposed to enable Motion in his Unreal Project?
