A bug in Microsoft Store is preventing to use Start - I already tried all the most popular "fixes"

Dario de Judicibus 6 Reputation points

I am really discouraged. I just bought a Dell G5 with Windows 10 to replace my old Lenovo because the operating system had become too unstable. I installed Office, Adobe Creative Cloud and Norton Antivirus and everything worked fine for a while. At one point Windows Update told me there were updates to install. I did, I rebooted the system and the ordeal began. The problem is well known, judging by how many people on the net claim to have it: the culprit is the Microsoft Store. There are three symptoms: 1. If I click on Microsoft Store, the window opens for a second and then disappears 2. if I click with the RMB on Explorer on the taskbar, taskbar’s jump list does not appear 3. if I click on Start, nothing happens Especially points 2. and 3. are a problem. So I started studying all the various solutions, but none of them worked. a. I launched "sfc /scannow": it works, there are no errors, but it does not fix the problem b. I launched "dism.exe /Online /Cleanup-image /RestoreHealth": it works, but it does not fix the problem c. I created another user: the problem occurred ALSO for the newly created user d. I used powershell to recreate the APPs: it reinstalled most apps, with few errors for few apps because the existing app had higher version or was in use Get-AppXPackage-AllUsers|Foreach{Add-AppxPackage-DisableDevelopmentMode-register"$($_InstallLocation.)\AppXManifest.xml"}: it does not fix the problem e. I launched "wsreset.exe": I got error ms-windows-store:PurgeCaches - app did not start I also tried several other strategies I found on Microsoft sites and forums (for example, permissions). No result. So I used the Media Creation Tool to get the latest version of Windows reinstalled from scratch. It was a mess because it gave me ONLY the option to loose all apps and files, but I did it. From a newly installed Windows 10, I started the whole process again. Now the Microsoft Store was ok, as well as Start and the taskbar’s jump list. I reinstalled the same applications than before, very standard, common and famous applications, the same I had on my old PC, but again, after a couple of restarts, I got the same problem. I am really upset. The whole architecture of Start based on Microsoft Store is obviously weak and unstable. I have no idea what to do now. I do not want to reinstall for the third time Windows 10. I need a REAL SOLUTION, once forever. Maybe troubleshooting by Event Manager, but not the usual try & hope!

    1. Former. The Start menu does no appear, as well as FeedbackApp, the notification sidebar on right side of screen, and other apps. Version is 20H2, build 19042.746.
    2. See below
    3. No error in %windir%\Logs\CBS\CBS.log, just Info
    4. Restarting Explorer makes no difference

    Please note that I applied a lot of technbique to fix the problem, with no success. SFC gives no error. I also reinstalled Windows from scratch and for few hours the Store button was back. Then it disappeared again.
