Hi @Thomas Zuo
We meet a similar issue recently. This issue is not directly related with Microsoft Edge or any of its components, but it's usual to get general sign in related issues in Microsoft Edge.
You can try the following usual resolution to re-register UWP packages on the affected device, by executing this command:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
