[MOD RELATED] Error code 135:eaddea49:9259f12b

Hi @guyfawkeseve. Unfortunately, out in the wild there are many mods that are no longer compatible with the game, even in their most recent version. You can find out which ones you have that don't work anymore by doing a 50-50 on your Mods folder.

This means organizing the files there into bite-size batches and testing one batch at a time. For each test, delete the file called localthumbcache, then put only that batch in Mods. If your game opens, set that batch aside as "cleared" and delete localthumbcache again. If it doesn't open, take out half the batch and see if you're closer to finding the culprit. Remember to delete localthumbcache each time.

You'll find some 50-50 method tutorials online too. Once you isolate the file, you can go to Curseforge or the modder's own site (usually Patreon, Mod the Sims, or Tumblr, but some modders have a "home" elsewhere) to find out if there's an updated version. If there isn't, there may be another, more recent mod somewhere that will do the same thing.
