We need more details, but this appears at first glance to be a case of exhausting video memory. Much will depend upon your hardware and software mix, so Please provide ALL the information requested in the wiki "How to ask for help" article. Don't forget to identify things that do not appear in the "load order", such as the version of Windows, if you are using a "Steam" or "GOG" and/or "regional language version" of the game (even if you are playing it in English); using the FNV4GB Patch, NVSE and it's related plugins; replacements for textures (specifically their larger image sizes: 1024x1024, etc.), animations, or "bodies", etc.; and "post-processors" like ENB or SweetFX. It saves us playing "20 questions" and gets you a more specific answer more quickly. (The usual turn-around on post and reply in an older game forum is 24 hours.) Screenshots of the "load order" don't usually work so well because they tend to cut off or fail to display needed information and are hard to "piece together" into a complete and coherent picture.

* See "How to markup images (etc) in forum posts and comments" article for how to use "Spoiler tags". "LOOT" already includes those tags in the "load order" it copies to your clipboard, so you can just paste it's list into your post.

 

In the meantime, please see the 'Vanilla Load Order' entry in the 'First Timer Advice' section; and the 'Common Game Problems' section of the wiki "FNV General Mod Use Advice" article.

 

Because you do not have the issue until you load a "save game", it is entirely possible you have a corrupted "save game file". This is addressed under the 'Common Game Problems' section of that wiki article.

If the problem persists, then work through either the 'Solutions to Starting the game problems' or the 'Solutions to "Crash To Desktop" (CTD) problems' sections in the wiki "Fallout NV Mod Conflict Troubleshooting" guide.

I recommend anyone read the entire "FNV General Mod Use Advice" article to understand the differences between this game and others you may have experience with; especially if this is your first attempt to play a modded FNV or it's been more than a year since you last did so. It is designed for someone who has never played a modded PC game before, so it tries to avoid making any assumptions, is kept "up-to-date", and covers years of "lessons learned". It is NOT a list of various mods to install that happen to work on the author's machine. It addresses fundamentals underlying how to get the basic game and mods to work together.
