[edit to include the version of Fallout 4 running is 1.3 Beta.]
Problem:
Fallout 4 would launch fine one day, then crash after the launch menu on another.
Literally; nothing was changed (No Mods added/deleted, no updates whatsoever.)
Solution:
Right-clicking the Fallout.exe
[Usually in C:\Program Files (x86)\Steam\steamapps\common\Fallout 4]
Select "Properties".
Select the "Compatibility" tab.
Under "Compatibility Mode", choose "Windows 7":
Previous troubleshooting involved:
* Restarting the computer.
* Verifying the integrity of the local game files on Steam.
(Right-click Fallout 4 in your Steam Library, select "Properties", then "Local Files")
* Renaming or Moving the Fallout4.ini, Fallout4Prefs.ini, and the Fallout4Prefs_Custom.ini files to another folder. (The game creates new default ones if they are missing.)
Note: The files are usually located in C:\Users\{username]\Documents\my games\Fallout4.
Note: The files may not have '.ini' after them, and 'Fallout4Prefs_Custom' may not exist for older versions.
* Disabling Mods [if installed].
* Updating Windows, video card drivers, Fallout 4 itself.
