Why npm can't find module '../../package.json' even if it already exists - npm

Question

The problem: when I start using npm commands I see the same error:
node:internal/modules/cjs/loader:933
const err = new Error(message);
^

The same problem with npm i, -v, init and etc. The same error is when I start it from C:/user or in a project with package.json where all works before. node works correctly. What should I do?
