Corrupt Mods

I’ve been playing sims for years, i have an extensive mode folders and have just transferred from a mac to an MSI. i’ve out all my mods and tray and overrides onto a sandisk 2tb, When i tried starting the game i kept getting the notification Its “Unable to start” and gives me the extract mod that is corrupt, when i delete it another pops up, after hours of going through i realised that i had gotten rid of loads of mods that played fine on my mac, is there a reason for this IM DESPERATE.
