Array index out of bounds fatal error upon loading

[0rion]

I'm getting the error below and crash when my single player game finishes loading on The Center (not Lost Island). Hoping someone else has experienced and found a solution; I've sent 3 help tickets and all I've gotten is generic tech support that repeats all of the troubleshooting steps that I said I already tried in the help ticket.

I was able to load into another single player map with the same mods and gus.ini settings, and servers are working fine, so this is an error with my single player save on The Center specifically, not my pc, mods, etc. Any help is much appreciated.

What I've tried so far:

- validated files

- unsubscribed to all mods and maps, uninstalled the game, deleted any files the uninstall missed including the mods folder, reinstalled the game (and tried starting without mods after validating), reinstalled mods and validated files again

- replaced save files with an older backup (pre-error)

- checked for driver updates and optimized Ark in GeForce Experience

- verified that there are no hardware, software, connection, etc. issues with my device

ERROR:
