ok I get it, I did the same for a while.
next idea. (This will take a while but it depends on leveled list) (hopefully you didn’t do the quest leveled list)
make a list of your leveled list by writing them down on a piece of paper (or print them out)
and repeat the settler spawn and cross the outfits out when they work until you have a searchable amount.
Also for testing, I would use ESPExplorer (https://www.nexusmods.com/fallout4/mods/16718) it makes life a lot easier with this kind of thing.
if it crashes using ESPExplorer then you are really close to the problem. (so take note of what armor you are highlighting with this mod)
