I can confirm, i also have this issue. Did you find a fix at all? using version 1.9

I had quite similar experience, but with NeoForge version of mod. Game version is the same (1.21.1). After creating world with mw create server hanging and getting killed by watchdog, after booting it does the same. Deleting created world in multiworld config folder is fixing boot hanging problem, but it repeats if you use mw create again.
