Invincibility on character,Invincibility Timer on an object,Invincibility Timer

So recently I've been working on a game where you jump over obstacles kind of like a subway surfers. I added a button that pops up after you die and it asks you to spend coins to be revived when you hit an object such as a chair. The button does work as when you spend coins you re spawn back to where you were and I tried making an invincibility type thing for a certain amount of time such as 2 seconds so the player doesn't collide with anything. The whole re spawning back to its position works but the invincibility isn't working as the player is still colliding with objects, I've been trying to figure out how to fix it.
