FHE operations are typically more computationally expensive than classical operations due to their inherent complexity. As a reference, here is an approximation of the gas cost associated with each operation.
The current devnet has a gas limit of 10,000,000. If you send a transaction exceeding this limit, it won't be executed. Consequently, your wallet won't be able to emit a new transaction. To address this, emit a new transaction with the same nonce but the correct gas limit. In Metamask, you can enforce the use of a specific nonce by enabling the feature in 'Advanced Settings'.
