c# - time out when switching to a specific iframe

Question

I am having trouble switching to a specific iframe. time out occurs when trying to switch to the first iframe in the last step in the code below (//set macro).

I tried so many solutions such as increasing the time out from 60 to 120 sec, or adding:

chromeOptions.PageLoadStrategy = PageLoadStrategy.Normal; 
chromeOptions.AddArgument("no-sandbox");
