Problem with the map

I have enabled world partition. I created a level and saved it, after restarting the project, I got an error. Please help me to solve this problem, as this problem interferes with compilation

it says failed to import model, if the world outliner has an actor that is referencing that model, try removing it from the world outliner

I just created a world with the world partition function enabled, and for 5 days I have not been able to compile even an empty world. What’s the problem ?
