After installing mods is there any quick fix to browse corrupted files?

Windows 11 user here. Been playing the legacy collection this past week just as is, with the usual crashes everyone is experiencing here and there. Since I haven't played The Sims 1 since early 2000s, I wanted to experience the big world of mods, so I started light by installing skins. Many were imported in with no problem, but this morning, I went into a mass download of skins from the www.thesimsresource.com/ (which I hadn't used before) and now the game crashes right after the startup screen. Guessing a few skin files are corrupted and would love to know if there's a way to browse and find which ones to delete to get the game running smooth again. Or should I delete all of them entirely and hope for the best?
