AliasCollision

The object or state already exists; treat the goal as met or pick a different target

The derived EVM alias is already bound to another account. This descriptor cannot be registered safely; create a new hashed wallet and use its new descriptor.

Declared by the HashedAccounts pallet; it classifies to the semantic code already_exists.

Declared at pallets/hashed-accounts/src/lib.rs#L277.
