Hi just a quick hint that may be helpful for someone With my RTX 3080 i encountered few crashes both with using SKKFastNewStart as long i reach the gates of the vault or without shortly before reach the gates of the vault too coming from Sanctuary, with vanilla no mod i got no issue at all and i managed to understand rtx 2000 and 3000 are having some issues handling debris I installed this small mod Weapon Debris Crash Fix at Fallout 4 Nexus - Mods and community (nexusmods.com) - and everything now run smooth with no crash: maybe it can be a good optional mod for one of your modules thank you
