Game hasn't really worked since I first installed it about a week ago. Added some mods before first starting the game, which didn't work, removed mods, done multiple re-installs and cleanups to no avail. (with mods it actually worked "better", could go through character creation, change some of the options, start a benchmark...)
Crashes when starting a new game or a custom battle. Custom battle loads, but unit objects are flying all-over the place, as if something was wrong with the 3D positioning. Crashes when hitting ready. Menu is empty, only "Sound" title is visible.

Things I tried:

• Complete reinstall with cleanup (Program Data, Documents, steam folder) (multiple times)
• Updated GPU drivers
• Updated OS
• Updated MOBO drivers
• Reinstalled dependencies (.NET, C++)
• Ran all possible launchers with admin privileges

Have you tried verifying the game files? Is you GPU driver and OS up to date? Could you try to reproduce the issues on 1.8.0 build as well?

Problem the same on 1.8.0.

Followed this thread here:

In Progress - Crash when starting campaign or sandbox

Summary: I encountered this crash when I wanted to try out the game again after having paused a few months. I cleanly reinstalled the game two times now (as explained in other posts like here https://forums.taleworlds.com/index.php?threads/crash-on-new-game-start.441796/), safe mode doesn't...

And it works only when launching via Bannerlord.Native.exe.
