His grandson, the Duke of Cambridge, is the current president of Bafta.
William was due to deliver a speech via video, celebrating the resilience of the film industry over the past year, however he withdrew following the death of his grandfather.
Accepting her award, Youn said: “I am very honoured to be nominated and I’m the winner now.
“My deep condolences for your Duke of Edinburgh and thank you so much for this award.
“Every award is meaningful but especially this one. British people are known as very snobbish people and they approve of me as a good actor, so I’m very privileged and happy.”
