Game crashes immediately after i load back into the game after the crash happened for the first time. Here is the crash log.
crash-2023-10-17_08.15.42-client.txt

at me.jellysquid.mods.sodium.client.render.chunk.compile.pipeline.FluidRenderer.render(FluidRenderer.java:340) ~[rubidium-mc1.20.1-0.7.1.jar%23362!/:?] {re:classloading}
Found this in line 22 of my logs as well.

#644, as well as others, describe the same bug.
The game crashed because in one of the chunks, there's a Lava stream/block touching a transparent block.

I'm not on the mod's Discord, but from what I've read of the other reports, I think they're working on a patch.
One thing you can do for now is uninstall Rubidium, and load the world to plug up the problematic Lava.

Duplicate with #642 (an unofficial fixed jar is provided in the thread)
