Game Keeps Crashing -- Runtime Error Mentioned in DXDiag

@mskellyanne0  The problem could easily be how Sims 4 is using the runtime, not the runtime itself.  But reinstalling a runtime is easier than reinstalling a game, which is the probable next step here.

Before you do that though, please double-check your antivirus, whether it's Windows Defender or third-party software, for any Sims 4- or EA App-related actions.  I've seen a couple of recent reports of Defender causing in-game crashes, which is odd but certainly plausible.  Please also try playing with the EA App in offline mode and your computer completely offline just in case there's something about the game's connection to EA servers that's an issue.

If that doesn't help, please do a clean uninstall and reinstall of Sims 4:

• Put aside your Sims 4 user folder, the one that is or was in Documents\Electronic Arts and contains your saves, and rename it to something that doesn't include the words "Sims 4."
• Download Revo Uninstaller (the free version is fine) from here.
• Launch Revo, select Sims 4 from the list, and click Uninstall.
• Cancel the system restore point; you don't need it.
• Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
• Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
• Close Revo, and restart your computer.

Uninstall and reinstall the EA App while you're at it:

• Launch Revo, select the App, and click Uninstall.
• Cancel the system restore point.
• The EA App may open a window.  Click Uninstall, then in the Revo window, click Moderate under Scanning modes, and click Scan.
• Revo will present a list of registry entries.  Click Select All, then Delete: you don't need or want to preserve these entries.
• For the leftover files and folders, click Select All, review the list and deselect anything you'd like to keep (this is unlikely, but it's worth checking), click Delete, and you're done.
• Close Revo, and restart your computer.

Install the EA App, then create a new folder into which you'll install Sims 4.  The folder should be on the root level of the drive of your choice, for example C:\Games is fine, but not C:\Program Files\Games.
