This a v1.2 device, which previous worked.
I'm using Windows 11
Removed batteries, and ssd, and set the device to USB.
In device manager, I see it in the USB section as Audio Moth (winusb)
I see a green led on the device I hear the sound of a device connecting but apps do not connect.
Using flashapp, and a paperclip, I update to latest firmware. This does not help. I will try on a Mac or a Linus system...
Can you post a screenshot of the Device Manager information. This sounds like a driver issue. Make sure you have tried powering on and off your computer.
