/dev/input/by-id/usb-MNT_Research_MNT_Reform_Keyboard_4.0_US_LT_RP2040-event-kbd seems to be gone after my last upgrade.
The only keyboard-related file I can find is /dev/input/by-id/usb-MNT_Research_MNT_Reform_Keyboard_4.0_US_LT_RP2040-hidraw
EDIT: Nevermind. Apparently it’s been replaced by /dev/input/by-id/platform-noserial-event-kbd
