Hello! I am facing the exact same problem as mentioned above.
I have tried all steps mentioned, also i did a clean uninstall.
I uninstalled the game, uninstalled steam and went and deleted all Steam Folders including mount and blade folders in steamapps.
Then i deleted mount and blade folder in "Program Data"
I deleted mount and blade in my documents, also files in c:/username localapp folder. I searched my whole PC for anything with steam or mount and blade and everthing was gone.
After deleting i installed steam again, and then mount and blade on a different drive just to make sure.. I ran the game as Administrator but it still crashes after the intro...
I have tried for days and days looking for a fix.. but i cant seem to find anything.
Here is my crash log: 2021-01-20_13.11.29_d30085e878ea9e7a1ac2075247d4486b
Please help me.. - Thanks
