I had the same issue and found this, learning from you guys that it was the shotgun shells causing the issue I decided to open up my profile and Ctrl+F to find any mention of the id, I found 8 of them, I deleted 2 of them with the word cartridges in them and I was able to load up my profile just fine
here's both of the sections I deleted they may be different for you, I'm not sure this was really a stab in the dark for me that ended up working out :
{
"_id": "b25b7f7125b1db4f45ae624d",
"_tpl": "5d6e6806a4b936088465b17e",
"parentId": "77b6bda91dea43a142a7ab34",
"slotId": "cartridges",
"location": 1,
"upd": {
"StackObjectsCount": 4
}
},
{
"_id": "52407435b6cd07438052669f",
"_tpl": "5d6e6806a4b936088465b17e",
"parentId": "77b6bda91dea43a142a7ab34",
"slotId": "cartridges",

},
