Crash Report

This bug is caused by two factors:
Minecraft bug MC-266463
The compact vertex format

duplicate of #2004 & MC-266463
In my opinion, this is more a bug in Minecraft Vanilla than in Sodium.

Probably the only thing that can be done about this is to wait for the improvements to the vertex encoding scheme to come in Sodium 0.6. There just isn't enough vertex precision to correctly render these things.

For those who can't enjoy 1.21 update with that bug: there is a resourcepack that workarounds this issue.

This should be resolved in Sodium 0.6.0 since the vertex format has a lot more precision.
