Maven Nucleus cannot be damaged

first phase, after doing damage to about 75% of health the maven nucleus stops being targettable by my minions and I cannot damage it anymore, it keeps rotating and spawning bosses but I am stuck here.

Also the top right of the area cannot be walked through anymore, there seems to be an invisible wall

Bug report nr. 2.626.301.728
