the codes for transferring cards from quizlet to anki are all not working since the new update - would some be able to help please 
Did you used Quizlet to Anki 2.1 Importer with audio support
It should be working with Anki 23.12.1 latest release, or did you mean Quizlet new update?
What problem are you facing with it? a screenshot would be great
Are you trying to import audio files? There is a discussion going on, but it is not possible atm
