Failed to launch error/Fully Black Screen when using CC

I don't believe all these steps are necessary. Sure, I've repaired the game several times since Wednesday and created a new mod folder with a new cfg. Today I tried a more persistent approach, since the error seems to appear randomly. On the 15th attempt, my game loaded, including all custom content and mods! It might be relevant that I'm only in offline mode now, as I don't want to be caught off guard by another hotfix. Perhaps I'm just getting lucky, since I only have 55GB of custom content. The fact remains: 50/50 methods are a waste of time. My custom content/mods were up to date on March 17th, no creator reported anything as broken, and they're still working.

ChatGPT told me that I should merge my CC files.  That would make sense if I knew it was a problem with the volume of CC that I have.  I am not sure that the problem is that cut and dry, so I'm not willing to try that yet.  I avoid merged files. 

But, question for others with heavy CC...do you have many of your files merged?  I have seen people successfully loading with 50-60GB of CC.  Is there an actual limit of the number of files trying to load or with the size of the files?  I don't know.  My backup Mods folder is 155 GB, stored off on another drive awaiting a fix or a solution.
