Sims 4 Not Working With CC?

This exact thing happened to me.  I had loads of custom content and mods so it was difficult to figure out which mod or mods were causing the problem.  What I opted to do was to move all my custom content to a new folder outside the game.  I named it SIms4mods.  Then I proceeded to copy and paste only those items that I really use.into the actual game mods folder.  I made sure to reintroduce only objects like custom furniture, windows and doors, walls, makeup clothes etc.   I DID NOT reintroduce any game altering mods, ie custom traits, cooking ingredient requirement suppressors, etc.  Once I did that, the game worked fine.  I am guessing that one or more of those mods conflicted with the new patch since they were not made by EA.  Rather than take the risk, I left them out.
