Hi Richard Hammers.
Thanks for your post in Microsoft Community.
I have learned that you have reinstalled Windows multiple times on your computer, and as a result there are multiple duplicate computer device messages in the Connect to Windows on your phone.
Please make the following settings on your computer
1 Right-click the Start button and select Settings
2 Go to Bluetooth & devices>Mobile devices
3 On this page, delete the information from your cell phone.
Meanwhile, please try to uninstall Connect to Windows on your phone and reinstall it to see if it can solve your problem.
If it still doesn't work, please refer to the following steps to uninstall Phone Link on your computer using PowerShell
1 Type Windows PowerShell in the search box on the taskbar, right-click it and choose Run as administrator
2 Type in the following command and press the Enter key
Get-AppxPackage *YourPhone* | Remove-AppxPackage
3 Please search and download and install Phone Link in Microsoft Store, or download it through the following link
https://apps.microsoft.com/detail/9nmpj99vjbwv?utm_source=technave&hl=en-us&gl=en-us
After this try uninstalling and reinstalling Connect to Windows on your phone again to see if after this has resolved your issue. '
Thank you for your understanding and support.
