Sims 4 not responding as soon as I open it

@buckkiii  I don't know exactly what's going on either, but if you want, you can set your computer to create crash dumps, then upload one whenever the game crashes.  Here's how:

• Hit the Windows key, type "command prompt" in the box, right-click on Command Prompt in the search results, and select Run as Administrator
• In the window, paste "reg add "HKLM\Software\Microsoft\Windows\Windows Error Reporting\LocalDumps\devenv.exe" /v DumpType /d 2 /t REG_DWORD" without the outside quotes into the box, and enter
• Launch Sims 4, and wait for it to crash, whether you get a long play session or not
• After it crashes, wait for any crash dialogs to finish
• Then hit Windows key-R and paste "%LOCALAPPDATA%\CrashDumps" without quotes into the box, and enter
• Upload the last .dmp file to the filehosting site of your choice, and link it here
• When you want to undo the auto crash log dumps, open Command Prompt as before, paste "reg delete "HKLM\Software\Microsoft\Windows\Windows Error Reporting\LocalDumps" /f" without the outside quotes, and enter.

Personally, I'd feel like a ten hour play session was pushing it even with no evidence of other issues on the computer.  Sims 4 isn't really stable enough to trust that it won't crash in that time.  And I'd definitely save much more often no matter what—even without crashes, you never know when you might want to quit without saving and reload.
