Hey there @Comicbook23! So you can get an actors forward vector like this, you can just go negate it to point backwards.
Basically you’ve got a couple of options. You could disable the player movement, AI brain them for a second and have them path backwards. You could force the players controls to input only the opposite direction when overlapping your “turn around” volume. You could even just rotate them then force input to walk forward (this is prone to error so not the best idea).
