Sorry i crash again : https://gist.github.com/lampyr/8486875a5d639f0db246fda8fa0f2d2a

Someone has created an Entity wish return null as ItemStack in the Armor slots, but this is not allowed as of 1.11/1.12 where ItemStacks have to return ItemStack.EMPTY.

please try this version 26.3.281 It should produce a log output stating where the errors is.

sorry für die unannehmlichkeit mit dem NPE und danke :)
