In the last couple of days, whenever I try to use Adobe Acrobat Reader DC (version 19.012.20040) on my Macbook Air (MacOS Catalina, version 10.15.2), I've suddenly started getting a blank pop-up window appearing on top of the main Adobe window. Once the pop-up window appears (2-3 seconds after the application is launched), the application is frozen, the window can't be closed, and the only way to escape is to force-quit the application. This happens whether I try to open a specific document (any of several) or just launch the application itself, no specific document. My pdf files open fine in Mac Preview. Any ideas of what's going on, or how to solve it?
We are sorry for the trouble. As described the Adobe Acrobat Reader DC (version 19.012.20040) is freezing on Mac OS Catalina.
You are using an old version of the application and it is not supported on Mac OS Catalina, please try the following steps:

Thanks Amal. Although the problem went away a day or so after I submitted the post, it still seemed like a good idea to get the updated version of Acrobat Reader DC. So, I used the Acrobat Cleaner you recommended, then re-downloaded Acrobat Reader DC. Now the problem has returned, in slightly different form: When I launch the application, I can use it to open an existing document, but any other actions (including just clicking on "Acrobat Reader" in the menu bar to check the version #) causes the everlasting spinning color wheel. Any further ideas? Thanks.
I am sorry to hear that the issue reappeared. Please try to create a new test user profile with full admin rights or enable the root account (https://support.apple.com/en-us/HT204012) and try using the application there and check for the issue.

Thank you Amal. Once again, the problem seems to have gone away after a few days. I don't know why, but this time I think I'll leave well enough alone. If it reappears, I will do as you suggest. - John
