Visual Studio Code – Separate process is not creating in MS PowerPoint while creating in MS Word and Excel

We have designed Microsoft Addins for MS PowerPoint 2019 written in VB.net.
There I am trying to create separate process in MS PowerPoint to open a presentation/file using the given below snippet

 Dim objPpt As PowerPoint.Application
 Dim objDoc As PowerPoint.Presentation
 objPpt = CreateObject("Powerpoint.Application")
 objDoc = objPpt.Presentations.Open(processFile, False, , True)
 objPpt.Visible = True

but it creates threads of Parent file and does not open a file as a separate process where in MS Word I use the given below snippet

Dim objWord As Word.Application
Dim objDoc As Word.Document
objWord = CreateObject("Word.Application")
objDoc = objWord.Documents.Open(processFile, , , True, , , , ,, , , , ,, ,)
objWord.Visible = True

And it opens the word document as a separate process.

So I need to create separate process for each file/presentation in MS PowerPoint

Can you help in resolving this issue ?

Here are some more information about on which environment I’m working :

Operating System : Microsoft Windows 10 Pro

Code Editor : Visual Studio 2019

Technology : Vb.net(.Net Framework 4.8)

MS Office Version : 2019(32 bit)

    Word and Excel both allow multiple instances of themselves to be created.
    PowerPoint does not (other than as the result of an obscure bug).

    I would like to share the impact of trying multiple applications of PowerPoint. As per the Microsoft paragraph below it will be sharing the process so painting of Menu bar/Standard bar/Add-ins tabs must be sharing objects so you cannot perform operation independently. Performed operation will going to impact other PPT screen.

    Refer Link: About PowerPoint Instance

    Multiple instances of Word (Winword.exe), Excel (Excel.exe), and Microsoft Access (MSAccess.exe) can run simultaneously. Therefore, these servers are defined as Single Use (Multiple Instances) servers. Only one instance of PowerPoint (Powerpnt.exe) can run at any given time. Therefore, PowerPoint is a Multiuse (Single Instance) server.
