I'm seeing an identical issue when using PitchTap from Audiokit, so again it's related to microphone input and processing the audio. Sadly with the suggested work arounds PitchTap stops working.

My unity builds are now all classified as 'internal'. I cannot find the build setting that is doing it. I definitely didn't turn it on intentionally. it seems odd this problem just occurred a few days after the opposite problem is reported.
