Looks like your crash is related to Lux Via and Whiterun mods. Check for conflicts between Lux Via, Whiterun City Overhauls, and Open Cities if you have them. Also, try disabling DwemerFairy just in case—it might be affecting something unexpectedly. Your crash log suggests a lighting or navmesh issue, so testing without Lux Via could help narrow it down. Also, make sure DynDOLOD and Occlusion were fully generated for your current mod list before disabling them.
