Error with my code since I insert AkComponent in my one of my blueprint

Hi, I can’t manage to compile my game since I put akcomponent inside my blueprint. To make matter worse, the output log seem to indicate that the error come from the script even thougt I never touch them since I do everything with the blueprint system.

Here is the error or should I say, the two lines that seem the most relevant.

UATHelper: Packaging (Windows (64-bit)): UE4Editor-Cmd: [2018.06.27-20.34.13:286] 0]LogWindows:Error: Assertion failed: !IsUnreachable() [File:D:\Build++UE4+Release-4.15+Compile\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\ScriptCore.cpp] [Line: 1144]

I try the solution in this link

I managed to correct it with the solution above, but for some reason, when I open up the project right after, it did not worked anymore even thought I double checked and the correction were well saved.

Any Ideal how to correct this and what mean Assertion failed: !IsUnreachable():
