MuseScore Studio no longer responding to MPK mini 3 MIDI keyboard

I have had the MPK mini 3 MIDI keyboard for about half a year now and use it every time I write music in Studio. Starting roughly half a week ago, the keyboard no longer worked with MuseScore. The buttons would respond the same on the keyboard itself when interacted with (pads would light up red, screen would reflect dials rotating, etc.), but nothing would happen in MuseScore. I've checked by I/O and MIDI mapping settings and nothing has changed. I have no clue where this problem stems from or how to fix it. Any help would be greatly appreciated.
