Saves cannot be loaded after 1 session playing with mods.
Yesterday, I installed a handful of mods and continued a previously unmodded save. Everything ran fine, I hosted a game on Steam and one of my friends joined and was able to play just fine. Today, I am unable to load any of the saves from yesterday. After clicking "continue" or loading a save from yesterday, Satisfactory tries to load the save, but hard crashes while loading, with a Unity bug report generated.
I tried loading without any mods, and the same behavior occurs. List of mods below, and debug log
Mod Name Mod Reference Version
All Fluids are Gasses allFluidsAreGasses 3.1.0
First Person Vehicles FirstPersonVehicles 1.6.1
Mass Upgrade MassUpgrade 1.2.12
Race Timer RaceTimer 2.1.0
Save files from 2+ days ago load up just fine. Steam files have been verified.
I tried to go into the Satisfactory Calculator save editor to remove the Mass Upgrade tool, as there's one in my hand and one in the dimensional depot. I couldn't figure out how to delete items from those locations.
Any suggestions on what I can do to at least get the save working? Not the end of the world if I have to go back to playing unmodded. Thanks!

Solution
your options are to load a save from before you used Mass Upgrade or to use SCIM to to try to track down the specific belt connection in the world that is broken
