Thank you for your response! Over the weekend, since my posts disappeared I continued to look for solutions in the meantime. After your previous advice, I knew there was a hardware error. My computer, did not have an option for hardware search under "Hardware and Devices Troubleshooter", but I found a solution. I will post my steps, so you know what I have done so far, but also if anyone else is or will have the same issues as me.
The normal way to troubleshoot hardware issues on windows 10 and 11: Settings > Update & Security > Troubleshoot > Additional troubleshooters. Then, you select the hardware or device you want to troubleshoot.
If anyone else has the same issue as me, and don't have the option to troubleshoot "hardware and device" you can still do this by typing CMD in the search bar, open CMD, paste: "msdt.exe -id DeviceDiagnostic" without quotation marks and ENTER. Thanks to Stella on MiniTool for the help.
After running the troubleshooter I got the message: “SM Bus Controller doesn’t have a driver”. Meaning the computer could not find any chipset drivers, for what I learned. This could not be fixed using the troubleshooter, but according to device manager I had no chipset drivers at all. After finding the right chipset drivers for my motherboard and installing those I could actually play TS4 for hours. Windows crashed again yesterday with a new hardware error code, this I think was because of a windows update because it was fixed using troubleshooting and rebooting. I can see a few of the crashes happening within an hour from different windows updates.
Additional to your questions: It only crashes/crashed while playing, all error codes and crashes except the one saying that it was not properly shut down is while playing.
Since the crashing have stopped I believe and hope we have fixed the issue. However I will download 3DMark Demo if I keep getting different errors, and post again.
Today the only issue is that I cant place furniture in build buy, they disappear before I even have the chance to place them. I saw there was other threads with answers for this issue though, I hope this is unrelated and that I just have the worst luck playing this game.
I am so very grateful for your help! I would never have figured any of this out by myself.
