Runtime execution error message

Hello, I’m getting a new error message. Can anyone tell me how to resolve it? I’ve been seeing it daily lately and usually when I run again I don’t see it but now I’ve run it four times and it won’t go away. How do I resolve it? Please see attached image and error text below. FYI, I’ve been running this bot daily for two years and the error is new

Message text. Thank you:
