Wurst 7.46.1 not compatible with sodium 0.6.5?

is there some sort of fix to this or do I simply have to downgrade sodium?

Hey rip_ryth, I actually just published a backport of Wurst 7.46.5 for Minecraft 1.21.1, which works with all the latest Sodium versions: https://www.wurstclient.net/updates/wurst-7-46-5/?mc=1.21.1
