The game is working now however, my old save seems totally lost (the same behavior described in the initial report still happens when it is loaded). Oddly enough, the game wouldn't even launch when I turned my PC on earlier today but what I did to get the game working was first run the "SFC /SCANNOW" command in an admin-elevated command prompt. I was checking for disk corruption and that is the only command that actually detected/corrected any corrupt files. Then I made sure to run both the launcher and the Bannerlord.exe as admin, this was the change that actually got me into the game again. Although, this may only be a temporary solution given that the game has wavered between functional and unplayable due to crashes for the last week. Regardless, I'm hopeful that if I encounter another crash I will actually be prompted by the crash uploader this time.
edit: made a new save aaaaand the game crashes without the crash uploader every time I fight looters.
edit... again: Decided to make every single exe in the Win64_Shipping_Client folder set to run as admin and I can now fight looters. I guess problem solved... again... for now... maybe.
