Gulp can't process with "gulpfile.ts/"

[ZhMster]

I'm using gulpfile.ts in my root along with few packages, however it was being included in my src/ directory, so i decided to include them into a folder and so install packages separatelly in "gulpfile.ts/"

the "gulpfile.ts/index.ts" contains my gulpfiles along with few splitted files in gulp folder.

gulpfile.ts/package.json:

{
  "devDependencies": {
    "@types/archiver": "^5.3.3",
    "@types/cli-progress": "^3.11.2",
    "@types/fs-extra": "^11.0.2",
    "@types/gulp": "^4.0.14",
    "@types/node": "^20.6.3",
    "@types/through2": "^2.0.39",
    "@types/undertaker": "^1.2.9",
    "ansi-colors": "^4.1.3",
    "archiver": "^6.0.1",
    "cli-progress": "^3.12.0",
    "copyfiles": "^2.4.1",
    "del": "^7.1.0",
    "dotenv": "^16.3.1",
    "flatted": "^3.2.9",
    "fs-extra": "^11.1.1",
    "gulp-debug": "^4.0.0",
    "gulp-npm-files": "^0.1.3",
    "gulp-typescript": "^6.0.0-alpha.1",
    "json5": "^2.2.3",
    "through2": "^4.0.2",
    "tmp": "^0.2.1",
    "typescript-collections": "^1.3.3"
  },
  "dependencies": {
    "gulp": "^4.0.2",
    "ts-node": "^10.9.1",
    "typescript": "^5.2.2"
  }
}

I tried to use yarn update, yarn install and even tried reinstall all packages deleting node_modules and installing it again, but i've got no success.
