When playing on one of the Archon Hunt missions, if Sevagoth's Shadow dies during the mission, my entire game freezes (except for the other players and enemies)

[Icionix]

I was attempting to finish an Archon Hunt mission using Sevagoth, however, during a Defense mission on Cervantes (a pre-requisite before the actual main hunt) once my Shadow died, the entire game freezes. I've attempted the same mission 2-3 times and all attempts had failed due to this bug. I've uploaded a video to streamable of me re-creating the bug (apologies to the players I was playing with) and was successful, help plz
