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

Was the world created in 1.16 Pre-release 1? If so, worlds newly generated in 1.16 Pre-release 1 are corrupted beyond simple repair; read the moderator note on MC-187408.
Was the world created in Pre-release 1? If so then this MC-187408
I have a world that is generated in version 1.15.2 on a server.
I don't know if I have ever updated the server to 1.16 pre-release 1, but a few days ago I updated to snapshot 20w30a from around snapshot 20w22a and noticed that entering the Nether from the Overworld causes the server to suffer an "Internal server error" that kicks the player. The server would still run.
I turned to MC-187408 and checked the level.dat file using NBTExplorer and saw that Data.WorldGenSettings.dimensions of the Overworld, the Nether, and the End is identical to that of a newly generated 20w30a world using the same seed. Replacing the level.dat of this world by a newly generated level.dat has no effect and player data is intact. The Nether is still not accessible.
Did you use any special custom world gen settings? If so, please attach them to this ticket.
MC-185004is caused when the nether doesn't exist, which could be caused byMC-187364.I Tried To Reproduce This Glitch By Creating New Worlds, However The Nether Would ALWAYS Spawn In And The Game Would Not Crash
I Think That Either 1. This Is A Datapack Issue Or 2. A Custom Worlds Issue
Creating a new world and then relogging before going to the Nether triggers the crash. Going to the Nether in a fresh world without relogging first works. Looks like dimensions are not saved or loaded correctly.
No custom settings or data packs installed. Completely fresh hardcore world. There were some generation errors within the world as well - i.e. biomes cut off along chunks and such.
Yep, I did relog before visiting the nether.
Could it be related to
MC-187358?I found two possible solutions to this issue.
Option 1 (easier):
I simply created a new world with the same seed as the corrupted world. I then moved the level.dat from the newly created world's save folder to the corrupted world's save folder overwriting the data. This allowed me to enter the nether with no problem.
As far as I am aware of this should not change any blocks. It does however delete all items in your inventory, so you should place them in a chest before attempting this method. It's also worth mentioning that this method transfers gamerules, difficulty, time, gamemode, and some other information, so make sure your newly created world has the same world options as the corrupted one.
This wiki contains exactly what data transferred.
Option 2 (better option, requires NBT editing):
Create a new world with the same seed as the corrupted world. Transfer the NBT data from "Data.WorldGenSettings.dimensions" in the newly created world's level.dat to the corrupted world's level.dat.
This method will not change anything except dimensions.
Make backups!
