@Sophieee09 No, there's no software you can use to fix your mods once they're broken like this. Data recovery can be unreliable, but even copying mods from one drive to another doesn't always work, unfortunately. I've seen mods and custom content be corrupted during the transfer even when both computers were entirely intact.
If you still have access to the old drive and can manipulate files on it, you can try zipping the Mods folder before transferring it. But other than that, you're unfortunately going to need to redownload the mods and cc items that are broken.
