^{Originally posted by nitish14s March 31, 2024} I am trying to create a PSA app using WindowsAPPSDK (WinUI3). I have created it as a multiinstancing app and updated the Package.AppManifest of the app <Extensions> <printsupport:Extension Category="windows.printSupportSettingsUI" EntryPoint="$targetentrypoint$"/> </Extensions>

But when while opening from a IPP enabled printer to open this app on clicking the Printer Preferences, app is crashing with System.Runtime.InteropServices.COMException

Steps to Reproduce

1. Add the IPP Class driver (Add printer via IPP)
2. Associate the printer to the PSA via regedit by adding a new key "Association" and add a new value to the registry by adding the app details as in the below screenshot 3.Run the package app and click on Preferences button as available in the IPP Class Driver image given below
3. Observe.
4. ComException occurs
5. Attaching the sample along
