So I notice a few things - I would suspect NAC X might be the culprit. We have had issues with NAC X and certain cells in SS2 because of how it deals with weathers, including vanilla interior weathers or situations when there is no weather. This is only a suspicion because when you go into the memory lounger for remote management it takes you to a very unique interior cell - and weather changes might be causing a problem there - but again that's speculation. You could try to briefly disable NAC and see if that works, but obviously you would have to roll back your save after doing that because I once disabled NAC mid-playthrough before I knew that was something you should never do and it totally borked my game, but for testing purposes you can see if that's where the problem is coming from. If it is, you may not be able to use the memory lounger if you want to continue with your playthrough and with NAC X, but you could potentially complete the quest via console commands and move on.
I also notice that you have both PRP and Scrap Everything, and I'm curious about that because PRP largely functions to make the precombine system more robust to improve performance, but Scrap Everything breaks all the precombines, so there may be a more general conflict there.
