It was running fine the first time i run the modpack. After installing java 16 and adding a 1.17. instance i was running into issues with Enigmatica. First the pack wouldn't even load. After deleting and reinstalling java 8 and installing the (at that time) newest version of Enigmatica i got it to at least load again. but it won't open even a newly created world.

Why are you running .... 20 versions behind? Running with -Djava.net.preferIPv4Stack=true might help you in this case.
