@Sabr1n4W Can you please have a look at https://cloud.cypress.io/projects/w8t3fx/runs/1042/overview/ddfd84fa-4c5e-4aac-bc82-0bf912a60572?roarHideRunsWithDiffGroupsAndTags=1

I hope that the changes I made will fix this issue.

Test passed 50 times after the changes without fail.
Before the changes the test failed once in 30 runs.
