The  c0000005 is Windows for "access violation."  It means the program in question tried to access a memory address in way that's not allowed, but that covers a lot of ground.  Essentially, it tried to perform a function (read/write/execute) at an address that doesn't support that function; or at an address it's not allowed to access, for example in the protected Windows memory space; or there's a null pointer involved.  In some ways, the exact action the program tried to perform doesn't matter—the point is that it tried to do something it should have known wasn't possible or allowed.

That's why the cause is typically a problem with the program itself.  In this case, that includes not only Sims 4 but any mods or possibly custom content you've added.  If one of these files is improperly coded, it could try to access memory in the wrong way.  How exactly that happens is beyond my ability to explain since I don't know anything about coding, but you can imagine how easily this might happen.  When the issue is Sims 4 itself, a game repair should address it, although it's occasionally been necessary to uninstall and reinstall.  Mods are the much more frequent culprit though.

It's true that a hardware issue could cause an access violation, for example if a memory module or drive is damaged, data could be corrupted or unusable.  But in either of those cases, there are typically other symptoms.  I'm not saying your system definitely doesn't have a hardware issue, just that in the absence of any other symptoms, mods are still much more likely to be the problem.
