I had the same issue month ago. I solved it with unpair/unconnect all devices, reboot, then search and new connect

those little bluetooth dongles you plug in the usb suck. Always hit or miss with me so I put a proper bluetooth card in the machine with latest bluetooth version. Now I can walk to the other side of the house with my ear buds and still hear and talk on zoom

new bluez update fixed it
