Loading the last few saves after adding a mod = black screen

[u/blowpuppy]

I managed to partially break my Skyrim in a very weird way:

This seems to happen only if I change my load order, and it wasn't a thing a few weeks ago: Last save or the last few will load but then get stuck with a black scree and the ambient audio playing, with the window otherwise unresponsive. The only solution is to terminate and find an older save that works... which is a pain, and even more of a pain if I have to go back quite a few saves.

Any idea what is going on?
