There is not much to state here, so i will be quick.

Problem: When i try to make a world it kicks me to the title screen and there is no new world in the worlds tab.
Mods installed:
Macro keybinds
Dalek mod u44
World edit
Schematica
Too Many Items.
That is all the info i have.
Have you tried creating a world without the Dalek Mod? It could be an issue with your actual game, rather than the DM - run out of storage or something? I'd just try removing all your mods, seeing if that creates a world successfully, then add another mod and try again. Eventually you should find the mod causing an issue.
