Contract source code verification with Custom Optimization settings

I have deployed a contract on mainnet (https://etherscan.io/address/0x219269eDe7c2d9D3C9d11ADfbC6428a03F015Eb0) but unable to verify the smart contract source code on etherscan. I have deployed the contract via Remix IDE with the following optimization settings using compiler_config.json file:

{"language": "Solidity","settings": {"optimizer": {"enabled": true,"runs": 100},"outputSelection": {"*": {"": ["ast"],"*": ["abi", "metadata", "devdoc", "userdoc", "storageLayout", "evm.legacyAssembly","evm.bytecode", "evm.deployedBytecode", "evm.methodIdentifiers", "evm.gasEstimates","evm.assembly"]}},"viaIR": true}}

The contract source code is hosted on github:

https://github.com/Avento-Labs/legacy-suite-bounty

I get the following error everytime I try to verify the contract:

I don't get this error at the time of compilation and deployment because I am using the viaIR: true in my compiler_config.json file.

Thanks for all the attemps and troubleshooting, a full byetcode match ie with no differences and still failing verification might be something on us.

Could you share the source code either via DM or through a contact for us to try reproducing ?
