Acrobat desktop app not opening and blue circle swirling around

Hi @jobenwin 

Thanks for reporting this to us. 

Is this a new installation? We assume you are getting this screen after launching the application.

Could you please try changing the following settings 

• Sect Acrobat as the default application manually. https://www.adobe.com/acrobat/hub/how-to-change-your-default-pdf-viewer.html 
• Click on the hamburger icon in the upper left corner.
• Click on Disable New Acrobat
• Or change the protected mode settings: 

Acrobat>Preferences (Ctrl)>Security (Enhanced)>disable "Protected Mode at Start-up", "Protected View," and "Enhanced Security">OK>close and reopen Acrobat [Windows only ]

 Check if this doesn't make a difference, and share the following logs with us:

 Procmon Logs: [Windows only]

Note: share the logs by uploading them to any cloud storage.

Thanks,
