[CURRENT ISSUE] Sims 4 Failed to Launch Game

RavenWyn​  Before you give up, try the clean boot again but with all peripherals disconnected other than the keyboard and mouse.  It's worth a shot anyway.

If that doesn't help, I could look at a crash dump, that is if the game generates one.  And if I don't see anything useful, I can ask someone else to look it over as well.  If and when you're interested, try again to play so you get a crash.  Click Windows key-R and copy and paste this:

%LocalAppData%\CrashDumps

When you enter, you'll see a list of .dmp files.  If one of them is from Sims 4 or the EA App, please upload it to a third-party filehosting site (Google Drive, Dropbox, etc.) and link it here.  If you see a crash dump that was written at exactly the time the game crashed, I'd like that too.  But in either case, please only upload files from this most recent attempt to play.

If there is no Sims 4 .dmp file, you can enable them:

• 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 can play at all 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 a free filesharing site 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.
