Error in UiPath Studio

Hi Community,

I have procured a license of UiPath Studio recently for my office work. However after getting it installed, when I am trying to do some automation of few office applications, it is throwing me various errors.I have consulted with several UiPath developers/consultants however did not receive any resolution.
Invalid%20UI%20Node


Hence kindly have a look into the errors and suggest me if there are any changes i need to do in my office firewall and anything else.

Regards,
Kaustav Chakraborty.
