I am using a HP Envy Laptop and upon opening Acrobat Adobe Pro, I am presented with a blank pop-up. Cannot do anything, no loading circle. I've restarted and updated my computer, I have used the Acrobat Cleaner and successfully removed and reinstalled the application with the latest update (3.06.2020), I have cleared my "%tests%" portion, and tried to what I could with no success in the end.
Thanks for sharing the troubleshooting steps performed so far.
From the description given above, if we get this right then this is the first time are launching the Acrobat DC and getting a blank screen upon launch right? Also, is this Acrobat DC or any other version?
Try the following steps and see if that helps.
1- Since its a Windows computer then, Open Task manager>check the Background processes> If you find Acrobat's activities there, then select and End Task
