Firstpersoncharacter mesh being rotated 90% when in play mode (pictures included)

I’m using Unreal 4.21.2 and the Animation Starter Pack. I was trying to setup up switchable 1st/3rd person cameras. Everything looks fine in the viewport of editfirstpersoncharacter, but when I enter play mode from the main viewport, the SK_Mannequin gets rotated -90 towards the camera. Does anyone have any idea what could cause this?
