Jorge, getting rid of the "Desktop" tab worked for a while, but Workshelf has gone back to crashing with no error message again. When I looked in the Event Viewer, there were two different Event 1000 Application Error events logged:

Code:
Faulting application name: WorkShelf.exe, version: 19.2.0.1390, time stamp: 0x5c819ca7
Faulting module name: Windows.UI.dll, version: 10.0.17763.168, time stamp: 0x10e22a9c
Exception code: 0xc0000409
Fault offset: 0x00065851
Faulting process id: 0x1798c
Faulting application start time: 0x01d4e9d0b9294c25
Faulting application path: C:\Program Files (x86)\Winstep\WorkShelf.exe
Faulting module path: C:\Windows\System32\Windows.UI.dll
Report Id: 08ade1d8-21fa-44b0-8518-e3cecbbf5b68
Faulting package full name:
Faulting package-relative application ID:


and

Code:
Faulting application name: WorkShelf.exe, version: 19.2.0.1390, time stamp: 0x5c819ca7
Faulting module name: GROOVEEX.DLL, version: 14.0.7113.5005, time stamp: 0x52b23fd0

Faulting process id: 0x1798c
Faulting application start time: 0x01d4e9d0b9294c25

Faulting module path: C:\Program Files (x86)\Microsoft Office\Office14\GROOVEEX.DLL
Report Id: 900150b5-81b9-40ce-ad05-7d932fb18834

What else can I give you that might help?

As you can see, the crash occurs at GrooveEx.dll.

This DLL is NOT a part of the Winstep application, it's a MS Office shell extension that is injected into the process space of the Winstep application.

It is known to cause problems with other applications (e.g.; see HERE).

If you don't need it, try uninstalling the 'Microsoft SharePoint Workspace' component of Office, as this is the component responsible for the GrooveEx.dll, or prevent it from running at startup.

Excellent. I have no use for Sharepoint. Removing it now.

Jorge, I don't know if you noticed, but Windows.UI.dll is ALSO causing Workshelf to crash. Not sure how exactly I can remove that.

It looked to me like the crashes were related. Just to confirm: is WorkShelf still crashing after removing Sharepoint?

Yes it is.

Exception code 0xc0000409 means STATUS_STACK_BUFFER_OVERRUN. Something is writing past the stack and corrupting memory.

Look, Paul, these type of crashes are extremely difficult to diagnose, especially those that do not happen for everyone. Normally this means the culprit is some 3rd party application that hooks into your application (i.e.; injects its own DLL into the process space of other applications) and eventually ends up causing problems or a crash when the host application does something that would otherwise be perfectly fine.

For instance, read THIS thread about MS Edge crashing on ntdll.dll (one of Window's main DLLs) after updating Windows 10 to the 1703 Creators Update. Almost by trial and error and another user with the same issue chiming in, they figured out that the REAL problem was in one case user virtualization software and in another device control client software. They both hooked into Edge and caused problems. Despite this, the small crash dump didn't mention the real culprit not even once.

I'm crossing my fingers that I MIGHT have found the issue. Even though I uninstalled Sharepoint, the Sharepoint ICON was still in the Office tab of WorkShelf, which is a Folder tab showing the contents of "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Office\".

When I opened the Office tab, Office tried to reinstall Sharepoint. I deleted the icon and haven't had a crash since. We shall see if that was the remaining issue.
