I second this. And you have to remember to count in the DLCs.
However, later versions of the game .163 and later, can handle a massively much higher number of .esl files. (Because bethe$da wants you to buy every creation club mod they create)
This includes .esp files, that are flagged as .esl files.
Looking over your files, your loadorder.txt file has a total of 716 countable lines in it. 716 files that listed. doing a quick search for ".esp" in your file, with PSPad http://www.pspad.com/en/ found over 600 entries of .esp in your loadorder.txt.
 Actually, before you open that file in psp, I HIGHLY recommend that you make a backup of it, somewhere else on your computer, in case you hit a wrong key somewhere along the line and end up corrupting your plugins.txt file [/edit]
Now, however. I don't know how your installer handles things. But, the file that Fallout4 uses, is plugins.txt which is located "C:\Users\
I would suggest opening that file, with psp pad, by right clicking on it, and choosing pspad, as the option to open it with.
Then press the CTRL key, and the F key at the same time. A dialog box will open, put a tick next to Count and then type in .esp or .esl or .esm
and that will tell you how many entries of that phrase that it finds.
Now, however. IF you DO end up screwing up your plugins.txt file, one alternative is to simply replace it with the backup. Another option is to just delete the file, start the game through fallout4launcher.exe and let the game build a new one.
