[Solved] Why does the GUI not appear after the player dies?

Issue: I have a gun system I made. When I equip a gun, it works perfectly, and I can see the GUIs. When I unequip a gun, I can't see the GUIs, which is functioning as intended. However, when I die and equip the gun again, the GUIs no longer appear. I want the GUIs the appear again when the player equips a gun, even when the player dies.

Conclusion: Sorry if my code is a bit messy, hope people can see it. I removed the other scripts for the sake of relevance and length. I also had to remove a "Context" part of the post, apparently because it exceeded 10,000 characters, even if the character amount was clearly below that amount. As always, thank you for taking the time to read this.
