Steam Build won't exit on quit, due to AudioMixer timeout

I’m in UE5.1, I have a devmode packaged game on a private steam page.

When I launch the game, everything works well. Can play it normally. But when I am in the main menu (either right away or after gameplay) clicking the quit button just locks up the game and never exits. I have to use the Steam stop button to actually close the .exe

I took a look at the logs and am trying to learn how to use UE insights. But I can’t see what would cause a: Timed out waiting to flush the source manager command queue (2).

I do see a buffer underrun .1s earlier, but I also can’t pinpoint why that is happening. I don’t hear anything on pressing the quit button, for all intensive purposes the audio is stopped immediately on quit.

Are there any insight options I should be using to track this? I think I currently have all of them on haha, but now it’s sorting through the different lines and understanding what is going on.

Any help is appreciated, thank you

Small update, it looks like in UEI, that my button roll over sounds and my main menu music are still playing after EngineLoop.Exit is displayed in the graph. Idk that is better context. But I’m now looking into that as well
