Nitro Pro PDF Freezes When Opening Documents and Crashes Explorer

[Josh Barrett]

This issue started suddenly about a week ago and is impacting all users of Nitro Pro PDF in the organization. When you try to open a pdf it can take up 10 minutes and during this time both file explorer and nitro pro freeze up and are not responding. We have a mix of 13 and 14. I updated both Windows and Nitro to newest versions yesterday to see if it resolves issue and it does not. If I switch the PDF viewer to Edge the issue goes away. I can also provide the following event log that confirms Nitro is what is causing the issue. Please provide assistance:
