@Qbingbong I read your initial post again, and I wanted to clarify whether you've tried a new user folder. Meaning, did you ever move the Sims 4 folder that's in Documents\Electronic Arts, the one that contains your saves and other user content, to your desktop? I thought you had from your wording, but just in case you haven't, please try that now.
If that doesn't or didn't help, try playing while your computer is offline. You can sign into Origin and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.
If that doesn't help either, I'd like to see a crash dump. 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 from the last two or three days (after we started troubleshooting here) is from Sims 4 or Origin, please upload it to a third-party filehosting site (Google Drive, Dropbox, etc.) and link it here.
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.
During all of this, please continue to use a clean Sims 4 user folder, just so that there aren't any complicating factors.
