I'm not sure that I wasn't also having this issue with 1P 2.572. I am using Firefox. When I boot the PC and try and enter 1P mini the icon is greyed out in Firefox. If I click on 1P in the system tray I get the attached error message. Normally what then happens is that 1P disappears from the system tray and comes back a few minutes later without my doing anything. When it comes back the 1P mini icon in Firefox is operating again. That is issue #1.
Issue#2. Everything appears to be normal but when I click on a login in 1P7 mini absolutely nothing happens. The web site is not opened. Or a settings page of my Home page opens. When this happens, I open 1P app find my login and try to log in directly. This will typically open the web site but not fill in the data. The only way I have found to solve issue #2 is to reboot and hope for the best. I have not tried going into Task Manager and deleting 1P and then trying to start it again. I will next time I have the problem.
I run into either #1 or #2 probably about 30% of the time.
