Crash: sh_items.gnut #840 - Invalid settings asset (Steam & Switch)

I was trying to equip LMG skin for the rampage and I got this notification

“there was a problem processing game logic. Please try again.

sh_items.GNUT #840

ui invalid, setting asset

I am reporting a severe logic error tied to my account that is preventing me from playing the game. Whenever I open an Apex Packs, the game crashes with the following script error:

sh_items.gnut #840 [UI] Invalid settings asset "Something"

Issue Details:

On Steam (PC): The game freezes for several seconds and then throws the #840 error specifically when I click to open an Apex Pack.

On Nintendo Switch: The situation is even worse. I cannot even reach the lobby. As soon as I enter the Apex main menu/title screen, the error pops up and forces the game to crash.
