Bug in Mando beskar journey tier 4?

Hello all. I'm a newer player and I was working on the Mando beskar armor story and keep getting stuck on the 2nd wave of tier 4 against the at-st where it just completely freezes. The sound and background keeps playing but none of the participants do anything and I can't select any units. Is this a common bug or something new? I haven't found any information anywhere else so I figured I'd asking the masses. Thanks in advance
