Starfall Crater boss bug

Boss became invincible after his meteor fall phase, idk if it only has to do with flicker strike bugging him out tho because I was just holding right click the entire time lol

Edit 1: Also, when this bug occurred, he had an infinite duration on his laser and was immune to all damage and targeting :(.

I just encountered the same bug. Dark Knight seems to be stuck in an infinite laser phase :(
