Hello, I already solved the problem and you should correct it. The error is found in the “Full of life” aspect pack, that pack made it impossible for all users who had it to play that world. The problem is in that pack, “Full of life” which started with update 2.46. As soon as we changed the pack and used another one, we were able to play again. And when placing the “full of life” again, he repeated the same mistake. Thanks for your attention.
Thank you for your report!
