Console crash 8/12

Had this save for over a year I keep getting error code 109 and told to relaunch the game. searched it up and it’s related to mods and custom content, neither of which I have. Owning business won’t work, rentals and vets won’t either. Adopting dogs and cats won’t work. Game crashes constantly, thank goodness my auto save has been working but I had to forfeit the save I keep free to mess around in for a duplicate save.
