The sims 4 crashes everytime sim travels or exit the cas

@dumraen  This particular crash is a heap corruption error, suggesting a possible issue with memory or storage.  That's not definitive but at least strongly suggests that's the next place to look.  So please run tests on both, in either order, and let me know what you find.  For the drive:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste "chkdsk /f /r c:" without quotes, and enter
• You'll be asked to allow a restart; say yes
• When the scan is done, use this guide to find the results

You should be able to attach the report to a post as well.  Running chkdsk will take some time, so you may want to leave it while you're doing something else.

For the RAM, the gold standard is MemTest86, testing each module separately and in at least two different slots on the motherboard.

Since this is time-consuming, you can start with chkdsk and see what you get, and you can also use Microsoft's built-in memory diagnostics first:

I wouldn't consider a pass from this tool to be even close to definitive, but if it does flag an error, that's probably accurate.

Finally, I'd like to know what RAM you're using, by product number.  If you don't have that handy, you can find it on the modules themselves.
