I have two FMOD issues: I am using UE 5.5 and FMOD Studio 2.03.06 I have a music loop that gets lost when I restart UE. Like the reference to the event gets lost and I have to select it again. I tried setting it directly as a variable but it doesn’t help. I don’t know how to fix this. ![Screenshot 2025-11-06 105004](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/e/e47a0d3f5b609e538f583b1d7a63a434a35c42fb.png) ---

Did you also try to validate the FMOD Settings from the Project Settings? ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/3/3728bc7d35d6029e391412b787863f3d93097f1f.png)
