Won't fix for 1.17+, still launches with error messages.
Problem caused by MC-225505, which one resolution has invalid.

If you're still here that probably means you haven't bothered to read MC-225505 for a potential fix thats already been reported 38 times. At least read the Mod notice (in the yellow box).
