Just installed NVSE into my game.
Found out the hard way that NVSE beta version 5.0b3 is NOT compatible with the GOG version of FONV. CTD during chargen inside Doc Mitchell's house.
I initially launched the game without NVSE installed.
I completed all the tests and assigned my SPECIAL points, Doc walked to his front door, I made a manual save point, then quit the game.
I installed NVSE beta version 5.0b3, relaunched the game using NVSE via FOMM, loaded my save and then walked to Doc, got the chargen completion gear, and Doc started to walk past me. Immediate CTD.
Double checked things by relaunching the game through FOMM and reloading the save, same result.
Triple checked by directly launching the NVSE_Loader.exe, and same result.
So I figured it'd be worth it to downgrade NVSE and see if that works.
NVSE beta version 5.0b2 at least gets through chargen without CTD.
To test beta version 5.0b2, I relaunched the game using NVSE via FOMM, loaded my save and then walked to Doc, got the chargen completion gear, and Doc started to walk past me. No CTD.
I double checked things by launching the game directly via the NVSE_Loader.exe, and no CTD.
If you have installed beta version 5.0b3 then you simply overwrite it with beta version 5.0b2 and you're pretty well good to go.
As a basic safeguard, don't load a save that was made while you had beta version 5.0b3 installed.
Hope this helps
edit: fix typo
