My game keeps crashing randomly !

nellyrozayy​  Please ignore the VRAM suggestions.  Your graphics chip doesn't actually have any of its own video memory; it borrows from main memory (RAM) to do its processing.  And it has 4 GB set aside already, which is more than enough for Sims 4 even on ultra graphics settings.  Besides, many BIOS versions for laptops and mini PCs (which are in some ways just laptops in a different box) are too limited to allow you to access these settings.

For the failed Windows updates, please run a couple of basic checks of your system files:

• Click 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, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, click Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes, and enter
• Post the message you receive here

Restart your computer, open Windows Settings > Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

WoohooJuiceSim​  There's no evidence this is a VRAM issue, and there's no actual VRAM in this system, just main memory set aside for the graphics chip.  Plus, most mini PCs won't take a GPU upgrade at all—there simply isn't room in the case.  While an eGPU is an option in theory, that adds a significant expense and usually doesn't give the same performance as a graphics card installed the normal way.
