Re: [CURRENT ISSUE] Game won't Open says "already Running"
@RawrrDinosaur18 Your hard drive is critically low on space. I realize that the drive is small and you don't have a lot of options, but try to clear as much space as you can, ideally at least another 10 GB. The Downloads folder is a good place to look for files that can be deleted, and be sure to empty the recycle bin as well.
Your dxdiag also lists a number of BlueScreens. It doesn't say when they happened, but they could be related to the Sims 4 issues (or not). It's worth looking into though. Open a File Explorer window and enter C:\Windows\Minidump in the address bar. If you see any files there, please right-click on them and select Copy, then right-click on your desktop and select Paste. if there are multiple files, you can zip them together. Then upload them to a third-party filehosting site (the one you used just now is fine) and link them here.
