and if I remove the transform in my .swcrc file get this error:

ReferenceError: React is not defined

Also, I have tried different solutions found on the internet like add this in jest.setup.ts file:

import React from 'react';
global.React = React;

But I get the first error mentioned above.

Problem description:

As I mention Above it occurs when I tried to run a normal test with testing library, the other ones without React code works fine.

Research direction

Start with the example test, jest.config.ts, and jest.setup.ts, then reproduce the failure using the listed Jest, jsdom, React Testing Library, Vite, TypeScript, and @swc/jest versions. Compare runs with and without the transform, using the pretty-format and DOMElementFilter stack trace as evidence; done means the React test runs without either reported error.
