Audio input not working suddenly

I use an Allen & Heath ZEDi 10 audio interface with my Mac Mini. This Mac Mini is ~4 months old. I've had no issues with audio in the past, but all of a sudden today the audio from the ZEDi10 is not being picked up by the computer.

I can see that the ZEDi10 is picking up audio, but the computer is not seeing anything. It's connected via USB type C -> USB. I use Logic Pro when working on music. I've checked to make sure the computer is still hooked up to listen to the ZEDi10, and it is. I've made sure Logic Pro is using the ZEDi10, and it is.

The computer is seeing the ZEDi10 in the sound input devices, but just not picking up any audio from it. I've tried multiple USB -> USB type C cables to no avail - they all get recognized by the computer instantly, but no audio. I restarted my Mac Mini in safe mode, but that didn't help. I have no idea why this suddenly happened. Is there anything else I can check?

The ZEDi10 is ~3 years old and I've never had issues with it before. Like I mentioned previously, the unit is getting audio from my guitar/bass/microphone/anything else. But, for whatever reason, it's just not making it to the computer.

Has anyone seen this before, even with a different physical audio interface?
