@RobinxxHouston There's no reliable software that will find broken mods, just conflicts, and even that is unreliable in both directions. (It produces false negatives and false positives.) So you'll need to test the files manually. As a head start though, there are two common mods that cause the game not to start in certain circumstances. One is NRaas Cupcake if the Store bakery set is not also present and loading. The other is the NRaas MasterController Progression add-on if the MC and StoryProgression base modules are not both present.
Other than that, you'll need to test everything. Use the 50/50 method if you have a lot of files to go through.
