How do I remove the effect of the character forcefield without removing the invulnerability?

Just want a character to respawn without those annoying effects

When a player respawns, set the Visible property of the Forcefield to false.

Just add a local script inside somewhere in the Player Scripts

local player = game.Players.LocalPlayer

repeat wait() until player.Character
game.Players.LocalPlayer.Character.Forcefield.Visible = false
