ArcMap: Errors on opening map documents

Hello. I recently started getting errors when loading map documents in ArcMap 10.6.1. I think this may be Python-related, because I was just working with running some Python/ArcPy scripts in FME. I've attached examples of the errors (System.ArgumentOutOfRangeException and System.NullReferenceException). In those errors there is a path referenced that doesn't exist on my computer. I can click OK on the errors and continue to use ArcMap, so they don't seem to be critical errors. ArcCatalog seems to run fine, and ArcGIS Pro does as well.


I've uninstalled and reinstalled ArcGIS Desktop and the errors persist. Any input would be much appreciated!


Update: looking again, I notice that the file referenced looks to be a C# file


Update 2: the errors don't show up when opening ArcMap alone, just when opening map documents. Given the path referenced in the errors seems to be related to Hazus, I uninstalled that as well. Still getting the errors. I also checked and Python seems to run fine (tested in command prompt, IDLE, ArcMap, ArcCatalog, FME), so that may have just been a coincidence that the errors showed up after I was working with Python/ArcPy in FME.
