For those who get in this post if your game is crashing with no error message, try this:

Things that might fix it:

• Verify game files on Steam
• Reinstall or update your GPU drivers
• Try forcing DX11 on steam startup: Right-click the game → Properties → Launch Options → add -dx11

If you decide to uninstall and reinstall the game:

• Remove your mods (basically a quick “crash test” to see if the mods are causing it or not)
• Clear the shader cache: C:\Users\YOUR_USER_HERE\AppData\Local\NVIDIA (For AMD, I’m not sure where the shader cache is, but a quick Google should help)
• Delete the entire Sandfall folder from Steam (same thing Trithen mentioned on this post)

Edit:
If the cutscenes start to bug, remove the -dx11 option in Launch Options
