PowerPoint file crashes PowerPoint upon opening

since this happens in some of the computers only, suggest that you open the file on working computer and copy everything and paste to a new powerpoint file.
most of the time it works to me. *Smile

 

screen recording using stereo mix in powerpoint

Hi,

Thank you for writing to Microsoft Community Forums.

1. May I know, if you are facing this issue on all the other sound applications as well?
2. Do you get any error code or error message when you try to record the audio?

We will have to try few troubleshooting steps to further eliminate the root cause of the issue.

Open Windows voice recorder and try to record any audio and check if that works.

If you still face the issue, try the steps provided below.

1. I suggest you follow this article on

PowerPoint 2016 high CPU usage after file is saved

Hi,

There's a possibility that an add-in that is installed and enabled in PowerPoint is causing the problem. For us to sort this out, we suggest checking the add-ins in PowerPoint and verify if a
CoPentaBar add-in is enabled. Follow these steps:

• Start PowerPoint.
• On the File menu, click Options.
• Then, click Add-ins.
• At the bottom of the Add-Ins dialog box, select COM Add-ins and then click
  Go.
• Click to disable the CoPentaBar add-in.
• Click OK.

Let us know how it goes.

Regards.
