Sorry that took so long, it seems like there are chain reaction issues going on. The two startup apps causing issues are OneDrive and Wallpaper64, the wallpaper engine app from steam.
There are also a bunch of services causing issues, either not allowing the save as function to work, or crashing COM surrogate, or both.
The services I boiled it down to are:
ASUS Com Service
ASUS System Control Service
Google Update
Various NVIDIA services
Stardock Start10
Teamviewer 12
