When I attempt to load the game it goes fine until i get to 6 out of 7 JEI loading recipes. Then it gets most of the way done and fails. The crash report says that it was cause by a JEI and the betweenlands

Im on 1.4.4 of mc eternals if that helps

that's most likely a ram issue, the pack needs at last 8gb allocated, for more Player Support go to discord, this issue tracker is only for pack issues, like a bad mod interaction
