The error you getting, i guess this is due to version issue. I hope above link will give you some good info to start with your testing.
instead of sending links for clarification. it is very much useful when you send the videos regarding the query, which was raised by users(smart Beam users) then they can easily understand the real-time working.
Send videos Instead of Links. for Refernce
If no videos exist, no videos can be sent. So, reference links are sent in order to at least give you documentation that you can use to figure out the problem.
As baxatob mentioned, you have overlapping windows meaning that you are trying to click on something that is being masked by something else. Usually means that, for some reason, the test case is not taking into consideration other windows, forms, objects, etc., that are coming up during the run of the application. Resolve that, and no more error.
