Windows 10: Can't start apps pinned to taskbar

Since the latest cumulative updates installed KB4562900 & KB4565483 I cannot left-click an app in the taskbar to start it. I have to right-click it, then choose the app from the pop-up menu. This applies to all apps pinned to my taskbar, all of which worked before those updates were installed.

Query re pinning and unpinning apps to taskbar

Pinning an app to taskbar does not remove it from Start all apps list. It list in Start under letter M as in Microsoft Edge, you should find it there even when it is pinned to taskbar.

I added a third step to the first suggestion, which worked for me:

1. Choose start> All apps,

2. Scroll to the application you want to pin, right click and then click
Pin to taskbar.

3. When the desired icon tile appears in the desktop box, left click on it and drag it into the task bar.

 

Can't pin to start menu/taskbar (SOMETIMES)

Ok I have been having problem pinning to the start menu since upgrading from 8.1 Pro to 10 Pro but have been ignoring it but it finally can to rest as an annoying problem.

The other day I upgraded Office 2013 to Office 365. After the installation was complete none of the short cuts were in my start menu or the all app list. I found the directory where they were installed and start clicking Add to start and add to task bar.
All the application pinned to start except Word, but I could pin it to the task bar. On the other account only a couple office application would pin to either. I ran a repair on office it did not help.

I was thinking it was a problem with office but now I am having other programs do this so it must be a Windows 10 issue (my computer).

Today I tried to pin Hyper-V manager to the start menu, it would not pin. Pinning to the taskbar worked just fine.

I can't really find a pattern to what will pin where and what won't.

I have run the scan disk and the repair and also the Dism cleanup-image and restorehealth.

Any other suggestions?

*** Edit

Ok looking a the file system the shortcuts seem to be there but I can't see them in the start menu. Is there a way to reset just the start menu or refresh it? I am assuming the shortcuts for the start menu are at the following location.

C:\ProgramData\Microsoft\Windows\Start Menu\Programs
