Corrupted save

[rocky helm]

Hello my save got corropted i guess? I have a bunch of broken weapons my skills dont work and nightrunner tools. Lost most of my items and also my stash is broken. This happened right after i finished the main story I tried installing some mods using nexus mod manager and it all broke down. I have no backups. Is there any way or someone to help me ? I want to play the dlc 🫠😿😔

Not much to do except try rollback
Rule 1. before using mods is to always make a backup. You can't come back later and cry if mods from nexus have ruined your save
