My game will sometimes launch & sometimes not with the same CC

ArchAngel_061​ Two questions:

Are you using anything like OneDrive or iCloud at all? Anything that syncs files? 

Does the game consistently keep loading okay, multiple times in a row, if you rename the Mods folder (also delete the localthumbcache file) and don't add anything to it?

My game was unable to launch with CC/mods (I debugged & updated everything) and now it launches with some CC (like 10 items) but also it’ll sometimes not launch, when I have changed nothing. It’s almost as if it can’t handle me adding anymore CC or practically 90% of my CC is corrupted (which I very much doubt) as I’ve been testing in bunches to find the “broken” ones, but it’s not consistent.

I just want to be able to use all my CC & mods, as my saves are basically unplayable without them. 

What i’ve tried so far: delete localthumbcache (multiple times), new mods folder, removed potentially corrupted save files, all mods are up to date/only using mods that are compatible with new update, enabled & disabled mods in game, repaired the game…. (i think i’ve done more, i just have forgotten as i’ve been doing this for hourssss)
