[2021] Unable to complete “The End” from War Eternal Living world mission.

I am currently working my way through Living World Season 4 and I just got to the War Eternal chapter. However I am encountering a bug during the first mission in this chapter that is preventing me from progressing through. I am getting stuck during the part of the mission where you jump on Aurene’s back and chase Kralkatorrik. When I have to use Aurene’s shield to prorate the my character from Kralk’a tail it doesn’t work properly. Kralk’s tail continues doing the same tail whip motion over and over again though it does 0 damage to me even when I don’t use the shield. It appears I am stuck on an endless loop of the same animation. I have watched some YouTube videos of the mission and I can see that when the mission behaves properly this shouldn’t happen. I have tried this mission on two different characters now and it gets stuck at the same spot on both characters. I did submit a bug request to ANet.

My question is, has anyone else encountered this bug before? And if so, what did you do to get around it? I really would like to continue the story and this is stopping my progress.
