How can I identify what is causing CTD?

[realmadridirl]

I have like 150 mods running so checking each one separately is out of the question for me. I'd honestly sooner just quit the game and not bother playing anymore. I don't get it, my game worked fine with basically all of these mods in my last playthrough but this time CTD everytime I try to talk to Codsworth in Sanctuary Hills after searching the area. I tried uninstalling any recent mods but still the same problem. Any suggestions? Novice modder btw so try keep things simple as possible. Load order is as follows

I´ve gone over your list 3 times, but there is nothing related directly to codsworth.

The only thing i could image is, you may have installed a mod, that needs other DLC, and you only have mechanist, as far as i can tell.

Do you run loot over your mod-list?

 

You may try to discard the first encounter with codsworth, move directly to Preston, and then go back to Sanctuary. Maybe then the conversation will work.
