My Game keeps crashing

Hey guys, I've been on this for days but I haven't figured it out I recently downloaded a mod that whenever I select a family  my game crashes. I don't know if I downloaded it from a website or redownloaded it from a mod I already had on curseforge. I suspect it's a script mod but not total sure.  I've done the 50/50 method but that hasn't worked and I have sooo many mods it takes forever to load. Any advise is greatly appreciated, please and thank you!
