I found a clue on Reddit that suggested I go to the Fallout 4 program directory (e.g.: program x86 / steam / steamapps / common / Fallout 4 / data) and search ccBG and delete the files. I did not have any files under that directory, so I checked in the main game install directory (SteamLibrary / steamapps / common / Fallout 4 / Data) and found several ccBG files there. I deleted all those and the game loaded.
