It looks like you are trying to do this multiple times.

Sometimes, I make mistakes on my testnet (upload wrong WASM). Then I use sudo to kill the storage.

Kill the ParachainSystem::PendingValidationCode storage.

    Extrinsic -> system -> killstorage. The default key is 0x45323df7cc47150b3930e2666b0aa31390d171f8401887cf06fb43a732994c32. If you modified your pallet name, then you should calculate the storage key youself.

Xavier is right, and I'll show you how to kill it.

  1. Get the storage key from chain state enter image description here
  2. Then kill it by system.killStorage (sudo or governance) enter image description here
