Error

Hello Error,

Welcome to Apple Support Communities! I understand you get an error saying it could not load Security & Privacy preference pane. I'm happy to assist you with this.

Let's boot into safe mode to see if the same thing occurs:

You can also test this issue in a new user account to help isolate the cause of this issue:

Best Regards.

I'm also having this issue.

I tired opening "Security and Privacy" when in Safe-Mode and the issue still occurs. When I attempted to log in using the guest account (to test with a another account) I was unable to log in.

Additional issues I've been having are:

-When I open Calendar, and attempt to create/edit dates, Calendar locks up and either takes minutes to load the information for that date, or won't do anything. Location data no longer loads when I attempt to enter it (map doesn't populate).

-When I try to open the new Music app, it doesn't open. It just continues to bounce on the dock until I force quit it.

Catalina 10.15.1

27" late 2012 iMac

3.2 Ghz i5

8GB Ram

I realize that this is close to the end of support date for this model for Catalina, I just want to make sure that this issue won't continue if I copy over my backup date to newer hardware.
