npm run build & npm start not working, react app - reactjs

Question

I am a new react student, have no place else to ask this question and can't solve it on my own because I'm really confused, I don't even know how to put this question together properly. I'm following the instructions from a react course.
I installed node.js, created a new project folder, then in the terminal I wrote create react-app . everything worked, and then wrote npm run build and npm start, but both didn't work.
Heres the error messages for npm run build:

some messages are in russian, if you need translation use the translator or ask me to leave the translation here, whatever you prefer
Thank you for reading this, I'm desperate and need help, nothing on the internet helped me just yet

Answer 1

I found something that works.
Using the command node node node_modules/react-scripts/scripts/start.js does the same thing as npm start, though I don't know what's the catch here. Works for me. Source: https://github.com/facebook/create-react-app/issues/8221

Answer 2

Firstly to create your project based on "create-react...."
You have to use the exactly command "npx create-react-app 'yournameProject'"
Then open your folder in a text editor like visual code and run the following command -> "npm start"
It shouldnt give you error
About your problem: I think you have stepped something
So try to use first "npm i" then "npm start"
