It might be related to non-deleted modding files. You can try verifying the game files. If that does not work you can try clean install.

Clean Install
The clean install is removing every single game-related file from your computer and installing the game again. Why do you need to remove the game while you just want to remove the modifications? Unfortunately, some of the modifications do not just add a new modules folder but also change or adds contents to the existent modules folder. Without a reinstall, we can't be sure those files are unchanged.To perform a Clean Install, Uninstall the game. You can do that by right-clicking the game on Steam Library and selecting Delete Local Content. Delete all folders related to the game that remains after the uninstallation. The folders that might have files inside:
Steam: C:\Program Files (x86)\Steam\steamapps\common\Mount & Blade II Bannerlord
Epic: C:\Program Files\Epic Games\Mount & Blade II Bannerlord
C:\Users\USERNAME\Documents\Mount and Blade II Bannerlord
C:\ProgramData\Mount and Blade II BannerlordNote: You'll need to allow Windows to display hidden folders and files to see the ProgramData folder and its contents.
