Torso not a valid member of Model?

So I found an uncopylocked place on Roblox: Link - https://web.roblox.com/games/271164303/Insane-Racing-Uncopylocked

Please have a look at it in Studio- This is related to my issue.

I was trying to use this game as a base for another game, so I tested this game out in Roblox Studio

Normally, I spawned in the game and I was looking at the output.

After 30 seconds, the map is picked. After the map is picked, the output says "Done"

A few seconds later it says "CHANGED X2" and "done agin" and after that it says "Not found" and Torso is not a valid member of model. So after looking at the code, I figured that it was not able to teleport me to the map. Can somebody help me fix me fix this error. Thank you!

Surely Because Your character is in R15, Try Switching to R6 ( Home > Game Settings > Avatar > R6 )

For More Info:

What is R15: R15 is an avatar body and animation rig in Roblox, which has more joints than R6 and is able to bend. The model is named after the number of body parts it has (15 parts) instead of 6 (R6)

What is R6: R6 is the default animation rig. R6 means "6 body parts" or "6 joints
