"cannot fetch metadata for null world" World crashes VRChat client every time you try to enter

I created a game world, it was working. I added some cubes, and now the world just crashes whenever you try to enter it. I tried removing the cubes, but still no luck.
I’m not getting any errors in unity. I checked the VRC Output Log, I get the Warning ‘‘Cannot fetch metadata for null world.’’ I also get ‘‘TerrainCollider: MeshCollider is not support on terrain at the moment.’’, but I don’t have a mesh collider on the terrain.

World is 53mb
