BUG

Current behavior:

Sometimes when I run all tests I have such error:

Important thing that I noticed If i remove tests "group_page.js" (check gif) it seems that the problem disappeared. "group_page.js" using different page: cy.visit(https://localhost:5002) for testing when the other tests that crashing using cy.visit(https://localhost:5000)

Check this gif, I had to run 3 times RUN ALL TESTS to make it work. Before always failed at login_page.js

I was trying hardcode url in cy.visit() (before I had url from cypress.json). The same result.

Steps to reproduce:

Run a few tests that include cy.visit(https://localhost:5002) for 1st test and cy.visit(https://localhost:5000) for 2nd test.
