Character can't move when placed in a new location

I’m trying to create a side-scroller game where if the player falls in the lava, they lose lives and reset’s the player to the spawn point. However, at the start of the game, the movement is fine, but, when the player falls into the lava, the player get’s set to the new location but the movement doesn’t work anymore. The animations are still playing but the player doesn’t move anymore. I’ve tried setting the movement mode to walking but that doesn’t work.

Note: the new location is in midair.

Thanks for your help.
