Laravel Dusk getting: "stale element reference: element is not attached to the page document"

Yesterday, I run my Laravel Dusk tests and they worked fine, today I run them and 8 out of the 13 fail, most of them with "stale element reference". I've made some modifications to the app but nothing that should require me to modify the tests.

I've updated the chrome driver using (thanks to staudenmeir/dusk-updater):

php artisan dusk:update 81

but that got me even more errors. Before doing that I got only 3 of my tests to fail now I've got 8.

I've tried googling the issue but nothing seems like a solution.

here are the first 3 errors I get:

1) Tests\Browser\ApartmentsTest::testApartments

the other errors are of the same type as "stale element reference".

Here is also my ApartmentsTest:

<?php

use Tests\DuskTestCase;
use Laravel\Dusk\Browser;
use Illuminate\Foundation\Testing\DatabaseMigrations;

    /**

     *
     * @return void
     */
    public function testApartments()
    {
        $this->browse(function (Browser $browser) {
            $browser->visit('/login');

            sleep(1);

            $browser->click('#ok')

            sleep(1.5);

            // select entrance
            $browser->click('.form-group:nth-child(3) .selectize-input')
                ->click('.form-group:nth-child(3) .selectize-dropdown .option:nth-child(1)')

                ->assertPathIs('/entrances/2/apartments')
                ->visit('/apartments/21/edit')
                ->type('percent_ideal_parts', 12.50)
                ->press('Запиши')
                ->assertSee('Успешно актуализирахте апартамента.')
                ->visit('/apartments')
                ->type('.form-control-sm', '#2020221101');

            sleep(1);

            $browser->press('Изтрий')
                ->acceptDialog()
                ->waitForLocation('/apartments')
                ->assertSee('Апартамента бе успешно изтрит.');
        });
    }
}

Any ideas appreciated.
