WinGet COM Server denies installation of non-UWP apps in Microsoft Store

Brief description of your issue

Can't install non-UWP apps in Microsoft Store, for example, Adobe Photoshop and Zoom, Store reports 0x80070005. However they can be installed through winget command line. This is not entirely a Store problem because Microsoft Store was removed and fresh installed countless times and when this happens the following logs are recorded:

Install state changing for product XPFD4T9N395QN6: Pending => Error
Exception Details: System.UnauthorizedAccessException

and an empty log file WinGetCOM-XXX.log is created in %LOCALAPPDATA%\Packages\Microsoft.DesktopAppInstaller_8wekyb3d8bbwe\LocalState\DiagOutputDir. Seems that WindowsPackageManagerServer refused the API call for unknown reason

Steps to reproduce

Try to install a non-UWP app in Microsoft Store, like Adobe Photoshop and Zoom

Expected behavior

The app installs with no problem, through both Microsoft Store and winget command line

Actual behavior

Store can't detect if the app is installed because access to package manager's COM server is denied, already installed apps always show a "Install" button, and click on "Install" results in 0x80070005 regardless of it is installed through winget command line or not

Environment

Windows Package Manager v1.6.3133
Copyright (c) Microsoft Corporation. All rights reserved.

Windows: Windows.Desktop v10.0.19045.3693
System Architecture: X64
Package: Microsoft.DesktopAppInstaller v1.21.3133.0

Admin Setting                             State

LocalManifestFiles                        Disabled
BypassCertificatePinningForMicrosoftStore Disabled

Start by tracing the Store installation path through the mentioned WinStore.App\Acquisition\InstallManager.cs, WindowsPackageManagerInstaller.cs, and WinStore.Core\Acquisition\PackageManager\WindowsPackageManager.cs locations, then inspect the empty WinGetCOM log. Reproduce the Adobe Photoshop or Zoom installation failure and identify why the COM server returns 0x80070005; done means Store detection and installation work for non-UWP apps without access-denied errors.
