3D model not showing in IoT TwinMaker scene editor

I have a digital twin built using TwinMaker, and this morning when I went into TwinMaker to add a tag to my scene, I could no longer see my 3D model that I had placed in my scene. Instead in its place is a red cube, and the scene object text on the left is red as well. Does anyone know what would cause this to happen and how I can make my model reappear in the TwinMaker scene editor? I have tried creating a new scene, I have reuploaded my model files to S3, I have replaced the model in my scene, and I’m still facing the same issue. Thank you very much in advance!!
