Sodium Crash or Freeze When Joining World: renderSectionManager is null

What the log looks like

java\.lang\.NullPointerException: Cannot invoke "me\.jellysquid\.mods\.sodium\.client\.render\.chunk\.RenderSectionManager\.scheduleRebuild\(int, int, int, boolean\)" because "this\.renderSectionManager" is null
at me\.jellysquid\.mods\.sodium\.client\.render\.SodiumWorldRenderer\.scheduleRebuildForChunk\(

How to fix it

  1. Remove known conflicting rendering and FPS mods from your mods folder, specifically Better Fps - Render Distance (betterfpsdist), Cull Leaves, and Starlight (which is obsolete on Minecraft 1.20+).
  2. If you have any utility, PvP, or cheat clients installed alongside Sodium, remove them completely as they break Sodium's chunk renderer initialization.
  3. Verify that your Sodium and Iris versions match your exact Minecraft version rather than relying on an older build across sub-versions.
  4. If the game still crashes or freezes on joining a world, temporarily test with only Sodium, Fabric API, and Lithium enabled, then add your remaining mods back in small batches to isolate the conflicting mod.
