Hey P.J.Vaught,
Hopefully I can help you here. Hit Windows key + I together and that should bring you into Windows Settings. Navigate to Privacy, then on the left pane, there is a menu item named Microphone. Click on that. Now find Instagram under Choose apps that can use your microphone, and check it on. At least, it appears for me, and it should be no different.
Let me know if you find it, good luck.
