Not able to load smart contract methods to fetch balance and make transaction in react native

[rajantwnabashuzph]

Provided that I have connected to a trust wallet via useWalletConnect().connect and received address and chainId. I want to run smart contract method, but the balance query stop responding. No process seen after step 3 below. Please refer to following code. I want to make sure same contract is working as expected in web enviroment

 const provider = new WalletConnectProvider({
        rpc: { 56: "https://bsc-dataseed.binance.org/" },
        infuraId: "898923b64bda482e9ee4608098aa12d2",
        chainId: 56,
        connector: connector,
        // qrcode: false
      });

      console.log("1: ");
      // await provider.disconnect();
      // await provider.enable();
      const web3 = new Web3(provider);
      console.log("2");
      let contract = new web3.eth.Contract(ABI, CONTRACT_ADDRESS);
      console.log("3: ");
      const result = await contract.methods.balanceOf(FROM_ADDRESS).call((err: any, result: any) => {
        console.log(err, result);
      })
      console.log("Balance of Account = " + web3.utils.fromWei(result) + " PETN");

      let amount = 1;

      const tx = contract.methods.transfer(FROM_ADDRESS, web3.utils.toWei(amount.toString(), "ether"));

      const gas = await tx.estimateGas({ from: FROM_ADDRESS });
      const gasPrice = await web3.eth.getGasPrice();
      const data = tx.encodeABI();
      const nonce = await web3.eth.getTransactionCount(FROM_ADDRESS);

      console.log(
        `Gas: ${gas} gasPrice: ${gasPrice} data: ${data} nonce: ${nonce} `
      );

      let trx = await web3.eth.sendTransaction({
        from: FROM_ADDRESS,
        to: TO_ADDRESS,
        data,
        gas,
        gasPrice,
        nonce
      });
