Confirmation bias accusations are themselves prone to confirmation bias; fear of confirmation bias is not sufficient reason to disbelieve something

Accusations of confirmation bias and cognitive dissonance are psychological assessments of people, not assessments of arguments. Assessments of arguments (straw men, ad hominem) are more legitimate. A vague fear that one might have confirmation bias is not a logical reason to change beliefs. The person accusing another of confirmation bias may themselves be exhibiting it.
