Tried running it in different ways: NVSE loader, NMM load options, Steam launcher Tried running the game without mods which do not use NVSE (NVSE still does not load)
Tried using several versions of NVSE, including the archived ones and the newest beta Added 'run as administrator' to fallout and nvse exe files Tried adding NVSE to anti-virus exceptions Nothing changed, I installed no new hardware. What's more, even on the same computer, not more then 5 months ago, I played New Vegas just fine. I used mods in Bethesda games since Oblivion and script extenders always worked for me.
