Existing World Keeps Crashing When Starting Server

[Kaludii]

My world is 6 GB and running on wine, when I try to start the server, it immediately crashes, but when I start a new world, it works fine, the world isn't corrupted. I get this error:

Is your world starting with the vanilla version aka no Element0?
