Prefab Error! Help please

Hello! I need some help with a certain error I have been getting on an avatar I am trying to upload. It says “Error while saving Prefab: ‘Assets/prefab-id-v1_avtr_3afa2d73-afff-497c-a86b-bff5393b9366_7341737274.prefab’. You are trying to save a Prefab with a missing script. This is not allowed.
Please change the script or remove it from the GameObject ‘Stylized Ralsei(Clone)’.”

I am not able to see a ‘Stylized Ralsei(Clone)’ inside the game objects or the inspector. There are other errors as well. Ty for any help that is possible!

Hello, it means that there is one of the prefabs that you are editing that has a missing script, so most likely package missing, did you have that issue before and have you checked if all the required script/packages installed ?

No, it imported perfectly fine, and I have all the required packages from the instruction sheet. The avatar came in a large zipfile that I also imported with the unity package, so I am unsure why its having an issue
