After install of Premium, I can't connect Windows Explorer to my iPhone

Windows 11 desktop, iPhone SE 16(I think)

I gave in to the offer of Premium Security, the price was a special. I downloaded and installed it, and when it came up for air, I wanted to connect my iPhone to my desktop, but it would not appear in File Explorer. I’ve been doing it for years, especially when I want to get a video transferred – emailing it to myself is painfully slow. The iPhone file system has always appeared, but not today. I rebooted the computer (that was part of the install) and then rebooted the phone, but to no avail.

Is this a known issue? Is there a fix?
