Enhance Audio is producing garbled results.

I use Adobe Express to make edits to small video files, mostly screen recordings on mac. I’ve used the Enhance Speech feature for years and it has always done a great job of cleaning up the audio and removing background noise. Sometime in the last few weeks that change. Whenever I use this on any clip at all, I get a really distorted robot-sounding effect. The results are completely unusable. Honestly, this simple video editor was the main reason I paid for this app. I can't actually use any of the outputs from this right now. I haven't been able to use a single video from this for over three weeks.
