Here's the error my friends and I get when trying to join one friend's world:
"Internal exception: io.netty.handler.codec.EncoderException: Failed to encode: Can't access registry ResourceKey[minecraft:root / minecraft:worldgen/structure]: Can't ..." and then it repeats over and over until it's off screen.
We've tried restarting it many times, restarting our computers, and turning off and on and deleting some mods. We added two since the last time we played, yet deleting those didn't solve it. We got our mods dirctly from curseforge, and here's a list if it helps: Biomes O' Plenty, Bovine's and Buttercups, Croptopia, Curios API (forge), ESSENCIAL mod, Fallingtree (forge&fabric), handcrafted, Moonlight lib, more mob variants, Resourceful lib, simple hats, supplementaries, TerraBlender (forge), the twilight forest, waddles, when dungeons arise - forge!, Xareo's minimap, Just Enough Items (JEI), and Traveler's backpack. the last two were the new ones I had mentioned.
If anyone knows what it means, I'd be very grateful! I'm not knowledgeable in reading code or errors at all, lol. Thank you!
