Script timeout in Protractor

My current scenario is: the user types the username, password, and click on the login button. Then, the next screen shows a list box with Stores to login. Protractor loads this list box but it does not find any element on it. And some times I get an error when I click on any element from this list:

Stack:
ScriptTimeoutError: script timeout
(Session info: chrome=84.0.4147.89)
(Driver info: chromedriver=84.0.4147.30 (48b3e868b4cc0aa7e8149519690b6f6949e110a8-refs/branch-heads/4147@{#310}),platform=Windows NT 10.0.18362 x86_64)

This is my spec file

describe('Stock Take Review', function () {
it('should do user login', function () {     

    browser.get('myurl');
    browser.driver.manage().window().maximize();
    browser.sleep(1000);
    element(by.id("mat-input-0")).sendKeys('user');
    element(by.id('mat-input-1')).sendKeys('Pwd');
    element(by.css('.full-width')).click();///////click on login       
    browser.sleep(1000);       

});
////////// Here the list box lists all the store, that the user should select

it('should select a shop', async function () {  
    let EC = browser.ExpectedConditions;
    let elm =  element(by.css('.mat-list-item:nth-child(1) .center'));        
    browser.wait(EC.elementToBeClickable(element(elm)), 150000);          
    await elm.click(); // select Koge store         
    browser.sleep(2000);
    await element(by.css('.mat-fab > .mat-button-wrapper')).click(); // click on the play button
    browser.sleep(2000);        
});

here is the config file

exports.config = {
  directConnect: true,

  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    "browserName": 'chrome',
        chromeOptions: {     
          args: ['incognito'],


        mobileEmulation: {
            "device": 'Zebra TC20',
            "deviceMetrics": {
                "width": 340,
                "height": 440,
                "pixelRatio": 3.0
            }
        }
    }
},

   // Framework to use. Jasmine is recommended.
   framework: 'jasmine',
 
    specs: ['../tests/StockTake_Review.js'],
    

  // Options to be passed to Jasmine.
  jasmineNodeOpts: {
    defaultTimeoutInterval: 120000
  },

Any help is really appreciated!
