Possible Fixes

Yes

Modpack Version

9-1.0.3

What happened?

Minecraft will launch, but it crashes shortly after the text "Reading World Data" appears when clicking create world or loading an existing world. This does not seem to generate a crash report in //crash-reports/.

I have tried the basic stuff, like memory allocation, and starting a brand new install of all the mods 9 (so there are only the base mods in it), but I still could not create a new world without it crashing.

I have also tried going back to versions 9-0.3.5 but the same issue persists.

Launcher: Prism Launcher 9.1

OS: MacOS 15.2

Hardware: M1 Max 64 GB

Instance RAM: 14 GB

You'll have to remove spark, as that has some issues with mac OS for some reason
