Wwise 2018.1.1 / Unity / Xbox One - APU heap could not be allocated

Question

I just updated to Wwise 2018.1.1 and now Wwise fails to initialize sometimes. It seems to fail about half the time. Any ideas? Here's the console output:

I have created an empty project containing Wwise only and this issue still occurs.

I'm experiencing the same issue on Xbox.

Fixed by changing "XBoxOne" to "XboxOne" in AkBasePathGetter.GetPlatformName()
