Unable to de-highlight on PowerPoint 2019 through VSTO plugin

Do not have enough reputation to comment on the answer by "Aleksey Malov" to query at un-highlighting text.

Preconditions: PowerPoint 2019 or 365. Presentation must be opened with window.

Original shape with highlight:

enter image description here

I'm opening a new PPT file from the VSTO plugin by saving a copy of original PPT file and then performing the following operations on selected shape object. I'm trying to do this using PowerPoint VSTO plugin with Office 2019. This works for me during debugging through Visual Studio but not through the installed plugin.

if(Application.CommandBars.GetEnabledMso("TextHighlightColorPickerLicensed"))
    Application.CommandBars.ExecuteMso ("TextHighlightColorPickerLicensed")

My queries:

  1. What does "Presentation must be opened with window." mean?
  2. Why does it not work in the installed plugin?
  3. If I attach the running PowerPoint process in Visual Studio even with Release config, I get expected result where highlight is removed. Any reasons why?

What does "Presentation must be opened with window." mean?

In the code you are relying on the CommandBars object which may not exist until the window is created. To get the code running correctly a window must be initialized.

Why does it not work in the installed plugin?

Well, you need to add some logging statements to see why YOUR code fails. Only looking at the log files you may find any difference.

If I attach the running PowerPoint process in Visual Studio even with Release config, I get expected result where highlight is removed. Any reasons why?

There can be multiple reasons. One of them is that VS could be run with admin privileges which causes all child processes to be run under the same security context. Files may not be accessible without admin privileges and etc.
