Macro is throwing runtime error 13 after 4 years of operation

Copper Contributor

Greetings,

 

I am running office 2016 pro plus. I have an excel macro that started throwing the runtime error 13 code today. This macro is in three separate sheets connected to 3 separate data sources running in a solid automation setup with years of service. The incoming data has not changed, nor have the sheets been modified. Is there an issue with an update maybe?
