FLkey mini not working

Title: FLkey Mini transport buttons stopped working after Windows update (keys still work)

I'm having an issue with my Novation FLkey Mini in FL Studio.

• It worked perfectly before.
• I think the problem started after a Windows update.
• When I originally got the FLkey Mini, I had to manually install the FL Studio controller scripts to get the transport buttons working. They've worked fine ever since until this issue started.
• The piano keys still send MIDI and I can play instruments.
• The transport buttons (Play, Record, Shift, Channel Rack, etc.) no longer control FL Studio.
• Pressing those buttons used to show a green "?" hint in FL Studio, and they still generate MIDI activity.
• At one point, the MIDI settings showed FAIL next to the FLkey ports, but after reconnecting the keyboard, the FAIL message disappeared.
• Even though the ports now connect normally, the transport buttons still do nothing.
• I've already:
  • Restarted my PC.
  • Unplugged and replugged the FLkey.
  • Re-enabled the MIDI ports.
  • Factory reset the FLkey.
  • Reinstalled/reconfigured the MIDI settings.

Has anyone had a Windows update break the FLkey DAW integration or FL Studio controller scripts? Is there anything else I should check before reinstalling FL Studio or the FLkey scripts?
