[SOLVED] ParserError: Source file requires different compiler version

I tried all that you mentioned in the discussion here (in other questions) and at https://github.com/smartcontractkit/full-blockchain-solidity-course-py/discussions/522 , however it is not solving the issue for me, I also noticed that the current compiler version remains (current compiler is 0.6.12+commit.27d51765.Windows.msvc). But when I right click and select Solidty:Compiler information, it shows 0.8.0.

from output:

Retrieving compiler information:
Compiler using remote version: 'v0.8.0+commit.c7dfd78e', solidity version: 0.8.0+commit.c7dfd78e.Emscripten.clang

Not sure if that is related to the issue I face. Anyways starting with the problem I see when running brownie compile. I get the error below:

I also tried to google some solutions so my settings.json file is a bit different but that didnt help too.

settings.json:

{
    "solidity.compileUsingRemoteVersion": "v0.8.0+commit.c7dfd78e",
    "solidity.defaultCompiler": "remote",
    "solidity.compileUsingLocalVersion": "d:\\Python projects\\Solidity dev\\demo\\smartcontract-lottery\\soljson-v0.8.0+commit.c7dfd78e.js"
    // "solidity.compileUsingRemoteVersion": "v0.7.4+commit.3f05b770",
    // "solidity.enableLocalNodeCompiler": false
}

In the brownie-config.yaml, I tried all the versions of openzepplin contracts too from old to latest (4.4.0, 4.3.0,4.3.2 etc), but same error.

brownie-config.yaml

dependencies:
  - smartcontractkit/chainlink-brownie-contracts@1.1.1
  - OpenZeppelin/openzeppelin-contracts@4.3.0
compiler:
  solc:
    remappings:

  mainnet-fork:
    eth_usd_price_feed: '0xaEA2808407B7319A31A383B6F8B60f04BCa23cE2'

I also tried to change the compiler in lottery.sol file with

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

Now I get a different error. Completely lost here :(

I am very new to programing in solidity and this is the first course I am following, I don't want to give up so easily, any help is much appreciated.
