Black Knight Verisium fight

Today i got my first star fall crater in a long time and the fight got bugged during second phase he started using his laser and he wont stop using the laser and become targetable again on my level 94 hexblast character at 2pm EST if you guys can pull the info to figure out how to fix this

I stayed in this fight for 5 minutes so you guys could have plenty of time to see the issue, i died and he's still firing his laser

When i died this way i was able to reenter star fall crater which ive never been able to do if i die in there.
