Try without 'eco'

i dont know what eco is?

[Luis_ST]

The error is caused by the worldgen/noise alternate_surface from namespace 'eco'. Eco could be a Mod or a Datapack you are using there are no more infos in the crash-report nor the log.

Could it be becouse i allocate to much ram to minecraft i have 16gb ram on my pc and i allocate 12gb do you think that could cause such freezes?
