Game crashing with Nether portals - java.lang.NullPointerException: Ticking player

      Moderator Note

      Worlds newly generated in 1.16 Pre-release 1 are corrupted beyond simple repair. The part of the level.dat file that stores dimensions has gone missing, meaning that these worlds do not have a Nether or End. slicedlime has a full explanation in this Pre-release 2 video here, along with some potential ways on how to fix it - though we thoroughly recommend to instead just discard the world.

      Built a portal, game crashed before loading Nether.
