Unreal 5.4.3 Audio stop playing as soon as it plays

Development Programming & Scripting

Hello, i have an application that plays an audio created runtime, after the Unreal Engine update 5.4.3 when the audio start playing, after few frames OnAudioFinished callback is called.

I tried to replace the UnrealEditor-AudioMixer.dll with the 5.4.2 one, it works in Editor, but after the build it has the same issue.
I also tried to compile the unreal engine 5.4.2 version and the groom doesn’t show any more on metahuman face blueprint.

How I can resolve this issue?
