(...had something all typed out and ready to post yesterday, but then InSim had server issues and I ended up losing it all... hope I'm not too late.   )

Try removing any content added since the last time you were able to play the game without it crashing in the catalog.  Also, make sure you don't have duplicate copies of the CEP file (_EnableColorOptionsGMND.package) in your Downloads folder.  You may have a hack or object that's causing an "continuous" error with your sims and keeping them "frozen" on the lot.

Plus, by looking at your zipped logs, I don't really see one that could help too much.  Try this:

   ::smilieiforgetwhi:: Load the game, and when you get to the neighborhood view of whichever neighborhood you choose, call up the cheat console (CTRL + Shift  + C) and type in boolprop testingcheatsenabled true and press Enter.

::smilieiforgetwhi::  After you do that, load up your "problem" lot and wait until it loads up completely.  If all goes as suspected, an error box will pop up right before (or sometimes after) the lot loads up.  

Take note of what type of error it is and the name of the error log that is dumped into the Logs folder.  That's the log that's most likely to help out in this situation.  And for a "quick" skip-over for passing the error by, click the "Delete" option when the error pops up.  It removes whatever object/sim that's causing the error.  If it's a sim, don't worry too much about it, as it's not a permanent deletion... you can easily get them back by either exiting and re-entering the lot, or by using the "Restore Family" option on the InSIMenator's summoner object.
