Hello all, I am currently having the same issue and yes have been able to isolate it using the skeletalmesh view, comparing my mesh with the blueprint mesh and indeed noticing that upon import the hip/pelvis bones orientations are indeed not matching.
The skeleton rig that is not working has come from Mixamo and was exported as .fbx via maya and 3ds max, both with Y-up and Z-up options toggled for exports but still have the same result that when simulating the level, everything seems fine but upon recording a take and reviewing it, the orientation is rotated by 90 degrees and staring at the floor.
Seeing as it is the skeletal mesh that the take recorder seems to be parenting to when its source is set to Player, is there anything within unreal I can do to adjust this orientation or a general fix to this? It looks like the above answer was a help in isolating the issue but if anyone has a suggestion on how to resolve this it would be GREATLY appreciated. Thank you in advance!
