Convert to World Partition seems to be completely broken in 5.7

So I created a brand new level and forgot to use the 3D world option, there's nothing in it, it's just a completely empty level . It does have a landscape though without an auto material. So I figured I would just go into window world partition and convert to convert it to world partition. So I closed it out and opened up an empty level I created from scratch. 5 minutes go by, it still is loading at 0% and has not yet finished creating the world partition, meaning that creating world partition is basically 100 percent broken. I tested this a dozen times with different variables. As of today I can't get it to work even once
