Can't use mods & CC

Hi guys, so my problem is I got a new laptop and decided to download Sims 4 again after ages. I used to always play with mods for creating characters and finished lots. So I have knowledge about sorting and implementing them. However this time when I downloaded it, only my old mods were shown even though I did not have some of them in my folder. So I tried many ways to fix it like reinstalling Sims 4 and moving my Mods folder and then readding it. Now my Sims 4 isn't showing any mods despite having the cc&mods function enabled. Turned it off and on multiple times but nothing is working. One thing to note is that I downloaded Sims 4 mods manager this time but that was another problem on it's own. I thought that might have been an issue but I've deleted it already and only used it while I was collecting mods and didn't touch Sims 4 during that time. I watched and read lots of videos and posts to figure out what my problem is, tried everything. I really want to get this to work because I spent so mch time gathering and sorting my mods. Also I don't feel like playing Sims 4 without them. I would be grateful if anyone could help me.
