Can not create user for admin panel - Error

Hello!
I am using Strapi v. 4.5.4 (Community edition) and i would like to create a new admin panel user via Administration Panel->users, but i get the following error

Additionally i attach you my package.json

{
  "name": "my-project",
  "private": true,
  "version": "0.1.0",
  "description": "A Strapi application",
  "scripts": {
    "develop": "strapi develop",
    "start": "strapi start",
    "build": "strapi build",
    "strapi": "strapi"
  },
  "devDependencies": {},
  "dependencies": {
    "@strapi/strapi": "4.5.4",
    "@strapi/plugin-users-permissions": "4.5.4",
    "@strapi/plugin-i18n": "4.5.4",
    "pg": "8.6.0"
  },
  "author": {
    "name": "A Strapi developer"
  },
  "strapi": {
    "uuid": "cca5fd00-83ed-4f25-8e1c-9d68076c4a4f"
  },
  "engines": {
    "node": ">=14.19.1 <=18.x.x",
    "npm": ">=6.0.0"
  },
  "license": "MIT"
}

Is that possible and how?

Additionally i figured out that it is impossible to create new Role via Administration Panel->roles due to restrictions of Community edition?

Regards

Please reach out to the administrator.

I just managed to create one user via admin panel right now, but Community edition has got the restriction not to create new roles.

Thanks
