lol I did this too just now.
Mine was from trying to be fully up to date, with SS3in1, Conq, looksmenu, MCM and F4SE
I had to roll back because it was a CTD feista of death.
And broken. Sim Settlements gear menu, with all the plots and stuff is gone.
New Vortex Profile.. enabling Sim Settlements, Conq, all current Conq factions + essential mods so fallout dont suck.
Got holotape from museum. Fixed.
Installed all addon-packs + Year 1&2
installed a bunch of random stuff (but nothing that effects build menu)
eg Kraggles, Workshop rearanged, homemaker
SS gear menu with plots etc, is still there.
