Duplicate key error

Disclaimer: I don't have a modules.log file. Used Windows search on the entire SPT folder and it couldn't find it. Uploaded something called "application.log" instead. Let me know where I can find it or if it's called something else and I'll get it uploaded ASAP.

Upon loading the game, I'm getting this error. I recently installed a few mods, so I tried removing them one by one to see which one was causing the issue. Ended up removing a mod (or two) related to a gun my PMC was currently equipped with, so that fucked everything up. I'm at a loss here. Any help is greatly appreciated.

Thank you in advance.

Identified the problem mod as KMC-Weapons, so I removed it, but now I'm getting this error.

You probably have something in your stash or a preset that can’t be used once you removed that mod, use the profile editor and remove those items or start a new profile/back up the old just incase

To no avail, I tried fooling around with it for another couple hours. In the end I decided to upgrade to AKI 2.0.*. Thank you for the response though. Mods feel free to move this one to the Trash Bin.
