When i try withdraw function i am getting the above error but other functions works very well. Can you help me?

Issue Description:
If hardhat node is re-executed, when you trying call the fund() function the console will throw a this error:

Nonce too high. Expected nonce to be 2 but got 3. Note that transactions can't be queued when automining.

Solution:
Patrick share a solution for his metamask version on 13:19:00, but in my version (10.28.3) the solution is:
Go to Metamask > My Accounts (top-right circle) > Settings > Advanced > Press the button "clear activity tab data" in the "Clear activity and nonce data" section.

This is quite frustrating and I am unable to proceed beyond this.

Hi everybody! 👋
I just started with lesson 8: HTML / Javascript Fund Me (Full Stack / Front End)
At the beginning of the lesson, i tried to check window.ethereum on the Chrome browser console and it showed me undefined 😕 although i have MetaMask installed and i was using it along with the course with no problems.
I'll keep following along with coding tho, and if any of you can help me with this, i'd really appreciate it.

In this section, following the tutorial should return the number 1, but I got the wrong text instead

CODE

function listenForTransactionMine(transactionResponse, provider) {
    console.log(`Mining ${transactionResponse.hash}...`)
    // create a listener for the blockchain
    return new Promise((resolve, reject) => {
        provider.once(transactionResponse.hash, (transactionReceipt) => {
            console.log(
                `Completed with ${transactionReceipt.confirmations} confirmations..`
            )
            resolve()
        })
    })
}

ERROR

Completed with async confirmations() {
        return (await this.provider.getBlockNumber()) - this.blockNumber + 1
    } confirmations..

after connecting metamask to local host as shown in tutorail. i am unable to fund my contract
snippet of fund function

async function fund() {
    const ethAmount = "0.01"
    if (typeof window.ethereum !== "undefined") {
        const provider = new ethers.providers.Web3Provider(window.ethereum)
        const signer = provider.getSigner()
        const contract = new ethers.Contract(contractAddress, abi, signer)
        console.log(contract)
        const transactionResponse = await contract.fund({
            value: ethers.utils.parseEther(ethAmount),
        })
    }
}

i revcieved two errors s in console of live server is

inpage.js:1 MetaMask - RPC Error: Internal JSON-RPC error
Uncaught (in promise) 

Hi! I keep getting the following error when i call the fund contract. And it also seems that when i call it once, it runs multiple times in my hardhat node (with the same errors coming out several times)

eth_call
  Contract call:       FundMe#<unrecognized-selector>
  From:                0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266
  To:                  0xe7f1725e7734ce288f8367e1bb143e90bb3f0512

  Error: Transaction reverted: function selector was not recognized and there's no fallback function

But when i check the console in my webpage, it seems to have worked (and i also got the transaction confirmations in metamask)

Is this normal? even though the contract calls are working properly with getBalance and withdraw

Hello Sir! @PatrickAlphaC and everyone I have an issue Kindly help me !

when I try to add a new network in metamask and add my RPC URL and ChainId it gives an error

Could not fetch chain ID. Is your RPC URL correct?

and when I try to save it shows
