Unknown Upload for Avatar Creation Appears when trying to upload a VRChat World

so i’ve been trying to update a Avatar work it was workign fine no problem until just recently after adding a mirror walls and roof(wall are cubes and roof is a plane) instead of gettign the VRC_ScenceDecripter upload i’m getting a differ upload that i cant Upload in like its some kinda error. i do have the Lastest SDK2 and was working fine 4 hours ago now its not any one have any advice how to fix this?

I remember having this issue, but I don’t remember how I fixed it.
I think in the end I had to make an entirely new project for it to work properly…

Edit, also make sure you don’t have any avatar descriptors in your scene.
