I am new to Blockchain and I was recently working on a smart contract, which deploys perfectly fine in remix IDE. But when I tried deploying it via Truffle over Sepolia test network, it failed. I previously followed a step-by-step tutorial for the same and even tried switching from HTTPS to websocket in my truffle.config file but to no avail. Kindly let me know where am I erring. I am attaching the ss of the output and my truffle.config file. If you need other details, do let me know.

* Use this file to configure your truffle project. It's seeded with some
* common settings for different networks and features like migrations,
* compilation, and testing. Uncomment the ones you need or modify
* them to suit your project as necessary.

* Hands-off deployment with Infura
* --------------------------------
*
* Do you have a complex application that requires lots of transactions to deploy?
* Use this approach to make deployment a breeze ️:
*
* Infura deployment needs a wallet provider (like @truffle/hdwallet-provider)
* to sign transactions before they're sent to a remote public node.
* Infura accounts are available for free at : https://infura.io/register
*
* You'll need a mnemonic - the twelve word phrase the wallet uses to generate
* public/private key pairs. You can store your secrets in a .env file.
* In your project root, run `$ npm install dotenv`.
* Create .env (which should be .gitignored) and declare your MNEMONIC
* and Infura PROJECT_ID variables inside.
* For example, your .env file will have the following structure:
*
* MNEMONIC = <Your 12 phrase mnemonic>
* PROJECT_ID = <Your Infura project id>
*
* Deployment with Truffle Dashboard (Recommended for best security practice)
* --------------------------------------------------------------------------
*
* Are you concerned about security and minimizing rekt status ?
* Use this method for best security:
*
* Truffle Dashboard lets you review transactions in detail, and leverages
* MetaMask for signing, so there's no need to copy-paste your mnemonic.
* More details can be found at :
*
* https://trufflesuite.com/docs/truffle/getting-started/using-the-truffle-dashboard/

I switched to Sepolia test net since Goerli isn't functional at the moment. I also changed the network ID for the same. I made a .env file wherein I have stored my MNEMONIC and PROJECT_ID as well. Regardless, I am unable to get the desired transaction deployment.
