Interface and targets issues PS5

I was doing a boss fight with my archer. The giant, for some reason, my character couldn't target him with her ascension skill. The the poison vial and my arrow went pass him. He gotta re target after I die. In certain times when I was doing a map, I couldn't pick up anything when I was by myself. And when I was playing with my friend me, my friend was for in the missing. Yeah, he dropped that unique belt, but i couldn't pick it up.
And we lost that item because of that he had it.So I can pick up items as well. The same thing happened to us in trials what we're near the boss. I was so alive, but it wouldn't let me interfere or do anything and my minions were still active. And where we tried to do the trials of chaos o can't join unless I go in frist or close the game and try to go back in it takes several tries
