Unfortunately, this is a common problem with any game which allows mods. The base game doesn't have a way to check each and every mod (with new ones coming out as often as people create them) to see which resources they use or modify, or even know about entirely new resources.

Sometimes there can be an outside program which can help determine issues (e.g. LOOT for Skyrim) but my general rule of thumb is if I use two mods that alter the same or similar assets, whichever one loads last will likely 'win', and I may end up with unexpected errors. If I want to avoid that, I avoid using mods which change the same things.

When more than one mod changes something that can end up causing a conflict like you're seeing because Mod #1 is expecting one set of values, and Mod #2 changed them to something else. Worse still, as a mod is developed and updated, it may introduce a new conflict which wasn't there previously, which sounds like what you may be experiencing.

It's time consuming, but you could try loading the mods one at a time to see which one(s) are in conflict and then decide what to keep and what to disable. Or if you have a lot of mods, take the 50/50 approach -- leave half of the mods on. If you have a problem, the issue is in the first half (and then you divide that in half again to find which 'set' of mods have an conflict until you're down to just one). If the first half didn't have an error, enable half of the remaining mods. Repeat in either direction until you find the 'problem' mod.
