Removing mods mid-playthrough is the quickest way to bork your save.

Depending on what platform you are on- you will need to fully vanilla your game.
For pc- I would recommend using this guide - https://discord.com/channels/98922182746329088/1324707994994217050/1346519587402813502

If you are on XBOX/PS - You can disconnect your mod.io account, or you can go to mod.io on a browser and unsubscribe and delete all the mods
you had been using and go from there.
