Adobe Acrobat Reader takes 30sec to open pdf.

After restart, my Adobe Acrobat Reader Version 2023.008.20555 | 64bit on Windows 10 works fine.

But after some time it takes 30 sec to open a  pdf, when I download it from the  Internet or when I use double click on some local pdf. (When I drag the pdf file into Acrobat window, it still works fine - opens it immediately).

 I have found that in that wrong state, an attempt to open pdf file starts new instance of the Reader, and after 30 sec it is closed and only then the pdf file is opened:

I have tried plenty of tips found on the Internet, but nothing helped. The only temporary solution is the restart of the Reader, but after while the situation is wrong again. What to do?
