Lost all guns but one in inventory after doing start quit to save progress

Earlier in the day I had been playing and had multiple purples and blues and I had to quit before completing the intelligences of the artificial quest and I come back and all my guns except one are gone! Normally I wouldn’t be upset but I wasted a ton of gold keys to get some decent gear to help me level up. Currently I am only level 12 and I know it doesn’t seem like much but this is very very disheartening. Any help would be appreciated.

I was also only playing offline and make sure to start and quit to always save progress.
