Glad we got this sorted for you.
Btw, pre-release beta testing FTW! It looks like the issue had to do with the sequencing of microphone initialization in our latest pre-release build. We've made a little tweak there to slightly change the ordering of when we initialize the microphone. Should prevent the issue from happening to others. 🙏
If you're on the beta, you can also solve this issue by changing your microphone to something else and then changing it back. This should fix the problem.
