Hello! I’ve been trying to upload an avatar for a friend of mine to use. However, I constantly receive a “Build Failed” error message. Here is the message from console: “VRC.SDK3A.Editor.VRCSdkControlPanelAvatarBuilder.Build (UnityEngine.GameObject target, System.Boolean testAvatar) (at ./Packages/com.vrchat.avatars/Editor/VRCSDK/SDK3A/VRCSdkControlPanelAvatarBuilder.cs:2060) VRC.SDK3A.Editor.VRCSdkControlPanelAvatarBuilder.BuildAndTest (UnityEngine.GameObject target) (at ./Packages/com.vrchat.avatars/Editor/VRCSDK/SDK3A/VRCSdkControlPanelAvatarBuilder.cs:2391) VRC.SDK3A.Editor.VRCSdkControlPanelAvatarBuilder+\<\>c\_\_DisplayClass104\_0.b\_\_3 () (at ./Packages/com.vrchat.avatars/Editor/VRCSDK/SDK3A/VRCSdkControlPanelAvatarBuilder.cs:1775) System.Runtime.CompilerServices.AsyncMethodBuilderCore+\<\>c.b\_\_7\_0 (System.Object state) (at :0) UnityEngine.UnitySynchronizationContext+WorkRequest.Invoke () (at :0) UnityEngine.UnitySynchronizationContext.Exec () (at :0) UnityEngine.UnitySynchronizationContext.ExecuteTasks () (at :0)” Any help would be much appreciated as this is such a headache! ---

You’re going to need to look closer at the errors that you’re getting on your computer. It’s good that you’ve ruled out pipeline id though. One less possibility ---

Sorry for the delay! I completely forgot I made this post. I did find a fix of it on my own. It involved making a whole new project in Creator Companion and importing everything from the last project into the new one. This seemed to have worked and I have yet to run into any issues. I’m sure there are better ways but this one at the very least worked for me! ---
