This is because there’s a permission to prevent a specific item or block from being used as a hat:
_essentials.hat.prevent-type.

Since operators have all permissions, they also have _essentials.hat.prevent-type.*_, meaning that they can’t use _any_ item as a hat. It’s a bit silly, but that’s just how it is.

To fix this, simply negate this permission for the group that has all permissions.
Example (if you’re using LuckPerms):
/lp group owner permission set essentials.hat.prevent-type.* false

This will let players in that group use any item or block as a hat. You don’t have to do this for the regular player group as regular players don’t have all permissions.
