    const contractWasm = contract_file.source.wasm;
    const contract = new ContractPromise(api,abi,contractWasm);
    const initValue = true;
    console.log("contract is :", contract);
    const tx = await contract.tx.new({ gasLimit, storageDepositLimit }, initValue)
    setContractAddress(contract.address.toString());

I'm sorry. It was a simple mistake. It was just that the correct answer was to use "CodePromise" instead of "ContractPromise".

Fixed code:

  const deployContract = async () => {
    const { web3FromSource } = await import("@polkadot/extension-dapp");
    const contractWasm = contract_file.source.wasm;
    const contract = new CodePromise(api, abi, contractWasm);
    const initValue = true;
    console.log("contract is :", contract);
    const performingAccount = accounts[0];
    const injector = await web3FromSource(performingAccount.meta.source);
    const tx = contract.tx.new({ gasLimit, storageDepositLimit }, initValue);
    let address = "";
    const unsub = await tx.signAndSend(
      actingAddress,
      { signer: injector.signer },
      ({ contract, status }) => {
        if (status.isInBlock) {
          setResult("in a block");
        } else if (status.isFinalized) {
          setResult("finalized");
          address = contract.address.toString();
          setContractAddress(address);
          unsub();
        }
      }
    );
  };
