Where is the upgradeable version of ERC1967 Proxy?

Support Contracts
5

Thank you for your reply @frangio . Im running into the "code size exceeds 24576 bytes" warning on remix even using the optimizer. Here is the snippet causing the warning:

function createTargetContract(uint8 _eventNumber, string calldata _seriesName)
    external
    payable
    onlyRole(DEFAULT_ADMIN_ROLE)
    returns (address)
  {
    TargetContract implementation = new TargetContract();
    targetContractImplementation = address(implementation);
    ERC1967Proxy proxy = new ERC1967Proxy(
      targetContractImplementation,
      abi.encodeWithSelector(
        TargetContract(address(0)).initialize.selector,
        _eventNumber,
        _seriesName
      )
    );
    contractsToOrganizer[implementation] = msg.sender;
    targetContractArray.push(implementation);
    emit LomEventDeployed(address(proxy));
    return address(proxy);
  }

What might be causing this?? I opened a topic regarding this here
