"an error on our end caused the launch to fail", game sometimes launches.

after the most recent update, my game has been finicky and would sometimes open, and sometimes not. i removed my entire mods folder to see if that would fix it, and it did.

my problem is that i have done the 50/50 method about 5 times in the same folder. i will take out the files, put them all back in file by file until i am given the error prompt. once i do this and find the CC causing the game to not launch, i will delete the cc that is causing the issue, and my game will load in. i will be able to fully load into the main menu.  however, after closing the game, i will be met with the error prompt again, (even though i closed out of the game and am not attempting to relaunch it). -

- when attempting to relaunch, i am given the error. this is incredibly frustrating, as all the mods and CC items i would put in the folder would work fine and i will recieve no error, and my game will launch...until i find the corrupted CC file and delete it, another one will be causing my game to not load, even when the game loaded with it before.

i am unsure what to do at this point and how to find the broken CC in my game, as these items will be in my mods folder, launch my game safely, then suddenly become corrupted. any help/advice is appreciated. thank you!
