Why does my iPhone 15 Pro Max not display content in the main Finder window when connected to a Mac running macOS Monterey?

iPhone 15 pro Max.

macOS Monterey v.12.6.7. Late 2015 iMac 27” so, unable to update O.S.

This has happened b4 ~ 4 times in the past 1 ½ years.

The only solution that has worked is to restart my Mac.

What does NOT work:

Restart iPhone

Restart Finder.

Plug iPhone cable into back of iMac USB port instead of into the USB Hub.

Unplug/replug or reverse the USB-C plug.

My iPhone does chime when connect to Mac

iPhone does appear under locations in left Finder pane with the eject icon on R side (which does not work.) I can also R click the iPhone & select eject & that also does not work.

Why does this happen?

I have the same peripherals plugged in 24/7, nothing changes when it stops showing iPhone info in R main Finder pane.

My iPhone still will charge.

It is a real pain for me to restart my Mac because I have multiple documents and a few finder windows open & many Safari tabs open.
