Game keeps crashing after installing Toddler Stuff pack

@sdb3z  The strange thing about the BEX errors is that they reference a component of a resource that Sims 4 supposedly doesn't use anymore, the 2013 VC++ runtimes.  That part of the error could be deceptive, I guess, but you can also try uninstalling and reinstalling those runtimes for good measure.  And of course the only way to properly test this is to reinstall the Toddler Stuff pack.

Hit Windows key-i, select Apps, scroll down to the Microsoft Visual C++ Redistributables, click on the 2013 x86 and x64 bit versions, and select Unintsall.  Don't touch any other versions.  You can download fresh copies from Microsoft here:

You do need both the x86 and x64 versions, but not the _arm version, which is for a different class of device.

Restart your computer before trying to play.

If that doesn't help, try playing in a clean user folder.  Move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content.  Don't add anything yet; just see whether a new save crashes the way your existing one did.  If the new save runs fine, you can copy over your current save (nothing else yet) and see whether it works as well.
