So, one bit of information. In Win 11, the device manager has a VIEW option of "Show Hidden Devices'. How convenient of Microsoft to hide things you might want to see. Once I checked this option, I can see the Ports in the device manager and it shows Arduino Uno (com3). I also installed the CH341 driver from NanjingQinhengMicroelectronics as described in a previous post. The install runs successfully although I can not see any results in the driver description shown under the Port listing in the device manager.
The Device Manager in Win10 says "Standard Serial over Bluetooth link (com3)" , no mention of Arduino. Strange.
Anyway, My issue is resolved, I ran the blink sketch from my Windows 11 laptop and it works. I'm not sure which step solved the issue but I appreciate everyone's indulgence. Thanks
