Wwise / Unreal Engine - Generating Wwise Sound Data Failed

Question

Hello everyone,

I tried WAL recently in Wwise Launcher and I would like to update the sound data from Unreal Engine because I update the original Wwise session but I got constantly "the generating sound wwise data failed".

I don't understand why it doesn't work, anyone found a solution to fix it and personalize the WAL project ?

Thanks :)
