Hi Anita! My name is Ben a fellow member here in the community and hope you are well!
With regards to this error, I suggest try checking if there are any updates for the app. You can also try the following steps:
- Open the Microsoft Store on your PC.
- Click on Library and then Get updates to see if an update is available.
- If an update for Phone Link is available, install it.
If there are no updates, the next step to try is to run a powershell command to troubleshoot the app
- Press the Windows key + X and select Windows PowerShell (Admin).
- Copy and paste the following command into the PowerShell window and press Enter: Get-AppxPackage Microsoft.YourPhone -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Once this is done, restart your device and try it again. I hope this helps somehow!
