Windows 11 desktop click network icon white window opens, does not populate, just an empty white box

I have three pc's in my room. All three suddenly started having the same problem on the same day earlier this week (noticed this behavior this past Monday - possibly the issue started a few days earlier, but only first noticed this Monday). 

I would click on the Network Icon on the desktop and a white box opens up with nothing in it, it never populates. This is what I see (see below)  - I can wait and wait and wait, but nothing happens. If I hoover my mouse pointer over it, a continuously rotating circle appears as if it's trying to do something. Now, I have researched a bit on the web, the only thing I found as a very temporary fix is to:

Press the Start button, type cmd, right-click Command Prompt, and select Run as administrator.
Type netsh winsock reset and press Enter.
Type ipconfig /flushdns and press Enter.
Restart your computer.  

Indeed, when I reboot, I click on the network icon, a box pops open and I can now see all the other pc's on my home network. BUT, when I reboot or turn off and turn on the pc, I'll click the network icon on the desktop and all I get is that odd white box again. 

Anyone have a clue as to what's happening and how to fix this issue?

I routinely apply all windows updates.

Thanks!
