Playhead is moving but nothing is recording

I am trying to do a simple, mono recording that I've done dozens of times, but for some reason Adobe won't record. When I click the record button, the playhead moves but nothing records (no waveform). My Sample Rate is 48000, Channels: Mono, Bit Depth: 16. I checked my audio hardware settings, and the input and ouptut devices are as they should be. The microphone (Yeti Blue) is lit up, so I know it is connected. Gain is turned up. Mute button is not on. My computer's privacy settings aren't preventing Audition from accessing the microphone, and the microphone array settings are normal. The Audition version I am running is Build 22.1.1.23. Any other ideas I can try?
