Phone link error 256 with S22 Ultra

I have had Phone link working for years with my Samsung Galaxy S22 ultra.

Recently, part of the functionality stopped working, specifically, the "open phone screen" part. I keep getting an error 256.

The phone is on Wifi, connected to a Ubiquiti NanoHD.

The PC is a desktop on 10 Gbps ethernet.

Both are in the same /24 subnet, using DHCP with IP reservations in the router.

The phone says it's connected to the PC. The PC says the phone is connected to it.

I can see the phone's text messages & photos on the PC.

I just can't open the phone screen on my PC, or show any app on my PC's screen.

    After reading all the suggestions and comments, I figured out how to get mine working again. I did a (save files) reset for Windows a few days ago, hence I have the latest Window update, but it was not working.
    So throwing all caution to the wind, I went to Older versions of Phone Link (Windows) | and randomly scrolled to the bottom of 2nd page and chose the October 2nd update (I know it was working then).

    I went through all the prompts to install that, including copying the code the pc gave to enter into the phone. Actually, I ended doing that process twice.

    Notes:

    * I did not regress the windows update but left it current

    * In looking at the "link to windows app" information, it showed that I had 2 instances of my computer listed (both showing disconnected). I thought this might be causing it, but just as an fyi there is no way to delete one, and so that's when I tried the method above.

    Hope this helps!
