Thanks for responding, I appreciate it. I know which key does run/sprint, I have played over 80 hours. I just installed game on new computer and this problem popped up. My keyboard is fine left and right shift work for run/sprint in some of my other games (Outlaws, SWTOR), but I changed out new keyboard for my old one and still same. I am left handed so I do make it the right shift, however, as I stated in my post I have uninstalled and re-installed game, tried left shift BEFORE changing anything, reset key bindings to default, changed key bindings, even switching to a different key instead of shift. Still no run/sprint. In this game you definitely do not want to walk, even on a horse walking is slow. I don't think it is a hardware issue, and everything else in the game works fine (except sometimes can't move/set camp), but specs are:
Ryzen gen 1 Threadripper
RTX 2080ti
32g ddr4 ram
Windows 10 home+
