Jest ReferenceError: You are trying to `import` a file after the Jest environment has been torn down

I am trying to test my APIs using jest.

I am having this error show after each time I run the tests

 PASS  test/auth.test.js
  √ Create a new user (237 ms)
  √ SignIn with user (133 ms)
  √ Delete The user (144 ms)

ReferenceError: You are trying to `import` a file after the Jest environment has been torn down.

my test file

const auth = require("../routes/auth");
const fetch = require('node-fetch');
fetch.Promise = require("bluebird");


(async () => {


    beforeAll(done =>{
        jest.useFakeTimers();
        done();
    })

    afterAll(done => {
        done();
    })

    jest.setTimeout(10000)

    test("Create a new user", async () => {
        const status =  await fetch(URL + "/api/auth/signUp", {
            method:"POST",
            headers: {
                'Content-Type': 'application/json;charset=utf-8'
            },
            body:JSON.stringify(SignUpReq)
        })
        .then(res => res.status)
        await expect(status).toBe(201);
    })

    test("SignIn with user", async () => {
        let status =  await fetch(URL + "/api/auth/signin", {
            method:"POST",
            headers: {
                'Content-Type': 'application/json;charset=utf-8'
            },
            body:JSON.stringify(deleteUserReq)
        })
        .then(res => res.status)
        await expect(status).toBe(200);
    })

    test("Delete The user", async () => {
        const status =  await fetch(URL + "/api/auth/deleteUser", {
            method:"DELETE",
            headers: {
                'Content-Type': 'application/json;charset=utf-8',
                'Authorization': 'Bearer <token>'
            },
            body:JSON.stringify(deleteUserReq)
        })
        .then(res => res.status)

        await expect(status).toBe(200);
    })

    

})()

The APIs test the actual database, not a mock DB

I tried

mongoose.connection.close()

jest.useFakeTimers();

changing jest timeout

adding done before and after all

using await before each expect

still, the error shows up

my env:

"node": "V12.19.0"
"bcrypt": "^5.0.0",
"bluebird": "^3.7.2",
"cors": "^2.8.5",
"express": "^4.17.1",
"jsonwebtoken": "^8.5.1",
"md5": "^2.3.0",
"mongoose": "^5.11.8",
"node-fetch": "^2.6.1",
"jest": "^26.6.3"

my DB is hosted on mongo atlas

How can I remove this error message?
