If I unplug the 2nd screen and reboot the computer, the internal display works.
As soon as I plug 2nd screen in, the internal display becomes "inactive" and I can't get it back on, even after unplugging the 2nd, unless I reboot.

I've tried uninstalling some recent windows updates and tried installing another driver for the "Intel Iris Xe Graphics" display, nothing works.
I contacted nathan working at geek squad tech support he suggested to update the driver, After updating the driver. The issue was resolved and now it is working fine without any issues.
