XPS 13 9370, certain keys not working correctly, requires multiple keystrokes

Hello,

Dell XPS 13 9370 - The built-in keyboard is not functioning correctly; the following keys require multiple keystrokes to work: 0 - p [ ; ' /

After several (~5 or so) keystrokes on the above keys, the keys will work - but for a short time. If I leave the laptop and come back, the same situation happens. I will often miss those letters when typing, which is frustrating.

Validated in the BIOS the keys exhibit the same behavior. 

I have validated that an external keyboard does work - no issues with those keystrokes.

Performed all recommended/critical updates from the Dell Support website on May 9, 2020:

- Chipset_Driver_DJT82_WN32_1932.12.0.1298_A04

Thanks in advance for your support.
