Trev,
I’m not a NINA or Primaluce expert but seems like you have to download the Primaluce “Play software” to allow their equipment to connect via Ascom

You may have already done this ??
Another thing to check is whether you have hidden unused assigned ports which may need to be cleared
Hidden Unused COM Ports or change COM port assignments*
You can clear hidden unused COM
ports by opening Device Manager , click View, then select Show Hidden devices
Under Ports ( COM & LPT ) expand to show assigned but unused Ports ( greyed out )
Right click and select uninstall
To change COM port assignments right click on USB Serial Ports , click on Properties, click port settings tab then Advanced , now choose an unused COM port from drop down list*
Finally an ol favourite, crappy USB cable
Cheers
