A bit more detailed answer for others that could encounter this issue :
Go to AkComponent.h
Comment out the line
//UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category = "Audiokinetic|AkComponent")
Go to AkComponent.cpp and rename
Compile your project, you should not encounter the problem again.
Note : this will prevent you from extending this function in blueprints as a consequence, but at least it allowed us to build again.
