Microphone no longer records my narration/virtual assistant can't help

Hello, I have had a terribly frustrating past two days trying to record my voice narration in a video I am trying to create. I should mention that my Blue Yeti microphone works just fine in Teams meetings. So it's not that. But when I try to add voice narration to my video, I get crickets. (Actually I get no sound at all.) I've been back and forth with the virtual assistants who are long on ideas but short on solutions. It's not trying a different browser (tried them all). It's not enabling/allowing access to the mic; been there, did that, doesn't make a difference. I've also gone into Windows settings and done all that business. Nothing helps or changes the situation. Nor is the first time that this has happened; it seems to happen regularly, unfortunately. I've created 3 or 4 videos in Spark and then 2-3 videos in ACCE, so I have done this a number of times. Sometimes I have trouble, sometimes I don’t. In the past, when I had trouble with the mic, I was able to sleuth it out with help from the virtual assistant. This time seems different. It seems like ACCE has fallen and can't get up (or I can't). This shouldn't be this difficult. Before I finally give up on ACCE, does anyone have any thoughts or suggestions? Thanks in advance ....
