@behzadz1 : Correct your hardhat.config.js like this :

networks: {
        rinkeby: {
            url: RINKEBY_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 4,
        },
    },

You did not put your networks inside networks{} thats why it is saying rinkeby does not exists

Just copy & paste the below corrected hardhat.config.js file.

require("@nomicfoundation/hardhat-toolbox")
require("dotenv").config()

const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
defaultNetwork: "hardhat",

networks: {
        rinkeby: {
            url: RINKEBY_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 4,
        },
    },

solidity: "0.8.9",
}

It will resolve your issue!
