Player can't run and jump while welded to another player

As the title says, when I am trying to run with a carried player (welded to me) I can not run and jump at the same time, video:

any help would be great!

Try and make the character you’re lifting so you can’t collide with it.

To achieve this, you can either set CanCollide to false or make a collision group with the physics service.

this is what seems to be the issue but I have put both players in the same collision group 1

Try and run a for loop to find the other player’s body and make it non-collidable.

this did not work as it set the parts back to what they originally were

Also even when they are in the same collison group and arent colliding it still breaks. But if they player is more then 4 studs away it works
