### What do you need help with? Bug report ### Installation method Unity Asset Store ### Issue area Build / Platform Compatibility ### Impact Blocker - I cannot continue ### Unity version Unity 6.5 ### Convai Unity SDK version 4.4.1 ### Target platform iOS ### Where does it happen? Only after build ### Short summary Scene crashes as soon as the Convai character is detected. ### What happened? I built a custom scene and even tried this with the basic sample scene in the latest Convai update on the Unity Asset Store (4.4.1). I am using Unity 6.5. The project builds just fine. When I run it on my phone (iphone 17 pro max) it crashes. This happens only when there is a character ID on the convai character. If I remove the character ID from the inspector, the project runs, but of course I cannot interact with the character. In XCODE, I get a break like this when it crashes: “Thread 70: EXC\_BAD\_ACCESS (code=2, address=0x140000001b)” on the break line below: 0x1158989d0 \<+13224\>: sub x8, x29, #0xd8 0x1158989d4 \<+13228\>: ldur x7, [x8, #-0x100] 0x1158989d8 \<+13232\>: bl 0x114c463f4 ; quant\_all\_bands → 0x1158989dc \<+13236\>: add sp, sp, #0x50 0x1158989e0 \<+13240\>: sub x8, x29, #0x60 ### Screenshots, recording, logs, or minimal repro ![Screenshot 2026-08-09 at 22.10.55.png](https://canada1.discourse-cdn.com/flex004/uploads/convai/original/2X/e/ed07b6e472be72ee195bb722b2a0437097104091.jpeg) ### I checked the relevant documentation, resources, and similar forum posts before posting. on ### I confirm that I did not include API keys, tokens, passwords, secrets, private character data, private conversation logs, or customer data. on ---

Hi, could you please check the generated Xcode project and confirm the library ordering? Go to: **TARGETS → UnityFramework → Build Phases → Link Binary With Libraries** or **UnityFramework → General → Frameworks and Libraries** Please verify that the libraries are ordered like this: 1. “liblivekit\_ffi.a” 2. “Libraries/libiPhone-lib.a” “liblivekit\_ffi.a” should be linked before Unity’s “libiPhone-lib.a”. Could you please confirm the current ordering or share a screenshot of this section? ---

1. Go to Project Settings → Player → Configuration → Enable Mute Other Audio Sources and Prepare iOS for Recording. ![S1](https://canada1.discourse-cdn.com/flex004/uploads/convai/original/2X/e/eb692fbe6800b72da63ef63453cf0c08373b6441.png) 2. libiphone.a might not be there, so you can set the first order to liblivekit\_ffi.a. ![S2](https://canada1.discourse-cdn.com/flex004/uploads/convai/original/2X/9/943c9ec9e4c595cb94a732f46c6a7b3fab211c2f.jpeg) By making these two changes, you can create a new build and have a conversation with the character. ---

It works well now. Thank you very much for your help. The only issue still is that the Hands Free mode always listens to itself and the conversation gets disrupted. Do you have a solution for that? Or is there a quick way to have a functionality to touch and hold the phone’s touchscreen to speak? ---

For a quick fix, you can follow the steps. Go to **Convai Manager** → **Advanced Room Control** → **Barge In** → **Client Speech Detection** and select Disable. ---

That one is by default Disabled. At the end the following adjustment worked for me both on the PC and on the iPhone. Thanks gain. ![image](https://canada1.discourse-cdn.com/flex004/uploads/convai/original/2X/4/415fd9d510c40da5997ad8da9da1572969236a8d.png) ---
