Trying to rig a new starter character, but it spawns on its side

For a new game of mine I’m attempting to use a custom R6 rig, so I set up the joints and dragged it into starter player. The problem is, every time I spawn into the game it is on its side rather than standing up straight. Does anyone know what might be wrong and what I could possibly do to fix this?

Is the HumanoidRootPart facing the correct direction?

How do I determine which way the HumanoidRootPart should be facing?
