Wwise 2022.1.2.8150 with Unreal 5.1 : Selected node not available ( issue just in build)

Question

Hello everyone !

On Wwise 2022.1.2.8150 with Unreal 5.1, I have an issue that happens in build but not in editor. Events are managed with auto defined soundbanks.

Sound works fine on the first part of the game, events are called at the right time, all good. At one point I'm calling a switch music container through an event, which transitions between playlists are handled by states of one state group. In Unreal, events are called successively to call states. However sometimes sounds cut abruptly but on different times in music transitions or the switch container doesn't play. A couple times everything worked from beginning to end.

In Wwise profiler (video attached), the error seems to link the issue to events loading. Below I paste the error, and again in editor I've not this issue.

 Selected node (382505979 (unknown)) not available. Make sure the structure associated to the event is loaded or that the event has been prepared                   

Thanks for your help !
