Answer 1

While Selenium tried to click on the desired element, something blocked it. This often happens when there are some animations or transitions.
To minimize such errors, I recommend using explicit waiters . This functionality allows you to wait for some event. For example:

• wait until the element appears on the page
  
• wait until the element becomes clickable
  
• etc. You can easily implement them yourself.
