immediate crashes on startup are almost always because of an esp trying to load resources that aren't there (You'd think they'd have a more graceful handling of this considering it's been an issue in bethesda games for a decade).
There might be some logging in FONV depending on what your setup is, I forget. But the fallback wya to debug that is to disable .esps until it stops crashing. With larger mods this can sometimes be difficult because you either have none of it selected or you have a handful of esps selected.
