Can no longer cast with Chrome on Inspiron 15 5510

"Cast" used to work with Chrome on my Windows 11 Inspiron 15 5510. It now no longer works. Selecting Cast from the "Cast, Save and Share" item results in a "No Devices Found" message. Cast works correctly when I try this on a Windows 10 desktop (not Dell). I have also tried to use Brave on the Inspiron 15 5510 and the result is the same "No Device Found" message.

I can cast from an Android phone.

All my computers are on the same local network.
