Can someone help me?

So I tried downloading a couple of mods for my sims4 and I downloaded quite a bit but when i tried to load my game it failed. Then I moved all the mods to my desktop and tried to play the game that way but when I opened it the front page wasn’t my household it was some new one that i haven’t seen before. So I pressed load game and pressed on my household that i had saved but it was loading for a decade so I dropped that idea and reset the game now when I try to do the same it won’t even let me go to the game directly but i go to the pick world thingy and when I press on the house where my sims lived at it doesn’t say anything just create a new household to move in even tho i pressed play game for a household already.. CAN SOMEONE HELP???
