Server crashes when creating a world with MultiverseCore

When I try to create a new world using MultiverseCore, the server starts to create the world, then it kicks me out and turns itself off. When I reopen the server Aternos tells me the world is corrupted. This did not happen before, although I had another server.

Plugins (7): LuckPerms, LuckPerms-GUI, WorldEdit, SkinsRestorer, WorldEditCUI, Vault (I don't actually need it), MultiverseCore

What do you mean by "recreating"? The log tells me the world is corrupt and if I try to delete it with Multiverse commands it tells me it can't delete the world. I have to go in the worlds section and delete it there.

Also, I tried making worlds multiple times and this always happened.
