same thing happened to me, with 0 update or any warning all mods stopped working.
Following advice here, I deleted the mod folder and redownloaded (updated) the mods I subscribed. Mods are now working again but the save seemingly already deleted them in my house(without compensation for paying the items, so basically huge waste of money AND time).
another update: - restarting the game - wanting to just save the look of my Zois to basically start all over in new save suddenly made the save work again with all mods in place.
No idea how that suddenly worked, but it did. So eventually deleting and reinstalling all mods, closing inzoi, opening inzoi, starting buildmode(where mods where working), starting create a zoi(where mods were working) and then loading the last save …. miraculously worked.
