Hello Murphy,
Thank you for reaching out to Microsoft community, I'm really sorry you're dealing with this, especially during such a critical time in your studies. first is make sure your system is fully updated,
Go to Settings → Windows Update → Check for updates after that check your Display Driver, Go to Device Manager → Display adapters then Right-click your graphics driver (likely Intel Iris Xe) → Update driver
If that doesn’t help, try Uninstall device → Restart → Windows will reinstall it.
let me know if it works by replying to this thread.
Cheers,
Jay Mark
