In a vanilla Minecraft Java Edition singleplayer world, I was able to apply an enchanted book with Frost Walker II to a Netherite Helmet using an anvil. The enchantment applied successfully, even though Frost Walker is supposed to be limited to boots.
There are no mods, resource packs, datapacks, or plugins in use. This occurred in survival mode.
Steps to reproduce this bug
Open a survival world (vanilla, no modifications).
Place an anvil.
Put a Netherite Helmet in the first slot.
Put a Frost Walker II enchanted book in the second slot.
Take the resulting helmet.
Environment
Windows 11, Java Edition, no mods or datapacks, vanilla single player survival.

Wait, nevermind. I can’t read. You said Survival. Would be nice if commets could be edited or deleted.
This cannot be reproduced in Survival mode. This is essentially a duplicate of MC-95555.
Not a bug. There are no anvil restrictions in Creative mode.
