When I try to connect to my Adobe account, after I am authenticated in the browser and go back to the application, I no longer can interact with anything (I get a beep sound as if the window was blocked by something or disabled though it's visual style doesn't change).
Even after I close it, there are processes left running in the Task Manager which I have to terminate forcefully in order to open Adobe Reader again.

This happens with the latest version 2023.006.20360 on Windows
