Hello Md. Saiful Islam Tareq,
Thank you for posting back and sharing with me the detailed information.
If this issue only occurs in PowerPoint App, you may try uninstalling PowerPoint and reinstalling it.
You may also reset S Pen settings. Go to the device settings and find the S Pen settings. Look for an option to reset the S Pen settings to default. This may fix any configuration issues that could be causing the problem.
If it still doesn't work, I do understand the inconvenience caused and apologize for it.
I sincerely recommend you raise a support ticket and contact Microsoft Online Support, they have higher permission and more resource to help you further investigate this issue and find the root cause. This is a more efficient way in handling this case for you.
