I think error used more for computer and other machine’s problem and issues for situations ( for example with people)

“Issue” has two primary connotations: 1) As a synonym for “problem” 2) As a synonym for “topic” “Error” simply means “mistake”. It doesn’t have any other meaning. If you want to say “cometer un error”, we say “to make a mistake”.

Issue it's the same that problem, situation, conflict and error refers to calculation situation
