Sims 4 crashes

@reebeckaaz  You don't need to translate anything or apologize for the Swedish.  All the relevant information is in Windows's language anyway, and since the format is the same in any language, I can find that info just as easily.

This is, unfortunately, just another access violation.  In case you're wondering, c0000005 is Windows for "access violation," which means the faulting module, in this case Simulation_x64.dll, tried to access a memory address in a way that is not permitted.  But aside from mod-related issues and a few in-game bugs, it can be pretty difficult to track down exactly what's causing this type of error.

So that means that the next steps are uninstalling and reinstalling the game and any resources it uses.  This is the order I'd suggest trying, but you can really try any order if you want, for example if you have slow internet and want to put off redownloading all of Sims 4.

As a first step, run a couple of basic checks on your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
• Post the message you receive here.  If that message is that sfc found corrupt files and was unable to repair some of them, please stop here and let me know.

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

To uninstall Sims 4 and Origin:

To uninstall and reinstall the VC++ runtimes Sims 4 uses, hit Windows key-i, select Apps, and scroll down to the Microsoft Visual C++ redistributables.  Click on each version from 2010, 2013, and 2015-2022, and select Uninstall.  Download new copies of each one from Microsoft:

2010:  https://www.microsoft.com/en-us/download/details.aspx?id=26999

2013:  https://www.microsoft.com/en-us/download/details.aspx?id=40784

2015-2022:  https://docs.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170

In each case, you need both the x86 and the x64 versions, but you can skip the ARM or IA64 versions, so that's six runtimes to install in all.  Note: all the runtimes are available in the last link, but the site sometimes gets weird if you're not signed into a Microsoft account, so I posted the other links too.  They're the same either way.

To uninstall and reinstall your graphics driver, please follow this guide:

I know this is a lot, but this one is being stubborn, and the usual easy steps haven't made an impact.  So it's time to do a clean sweep.  You can test after each step or do multiple at a time, whichever you prefer.
