UNEXPECTED_STORE_EXCEPTION bsod

Hi, I have a new Win11 computer built by Acer. I've had a few crashes during normal operations - playing a game, sometimes just using Firefox. I only managed to capture one minidump after getting that turned on, and I'm trying to figure out if it's a hardware or software issue.

I have attempted the following

  1. sfc /scannow
  2. DISM.exe /Online /Cleanup-image /Restorehealth
  3. Checking for updates in the system settings tool
  4. Updating my graphics drivers (NVidia)
  5. Running a memory diagnostic via Windows Memory Diagnostic
  6. Ensuring I have most of the bloatware installed with the computer removed (McAfee, Acer stuff)

The last several frames of my minidump look like this

And running !analyze -v in WinDbg, I see this as part of the output

 

CUSTOMER_CRASH_COUNT:  1

    Open the minidump; it will highlight the driver or component responsible.
