Question Keyboard inputting random letters, but only on bitlocker password entry screen

Having a bizarre issue where my keyboard inputs random letters but only on the bitlocker password entry screen. As soon as the screen comes up the field fills with letters, that Insert reveals as being random. Bitlocker recovery password works fine, as that screen doesn't allow letters to be entered, and once booted into windows my keyboard has no problems at all. Can enter my windows password and type normally with no problems. I have no USB devices plugged in, but Device Manager shows Standard PS/2 Keyboard as well as 3 "HID Keyboard Device" devices.

The device in question is an HP Elitebook x360 1030 G3.

Does anyone know what could be causing this? Thank you!
