Has anyone else got this issue? I've submitted it to Apple under FB7820658.
Whenever I open System Preferences and click any pane icon (Desktop & Screensaver, General, etc), the app hangs for a second and then presents me with a window titled “System Preferences Internal Error”.
When macOS Big Sur was first released as a developer beta, I installed it to a separate APFS volume first. I could use System Preferences fine there. I then booted back into macOS Catalina, deleted the Big Sur volume, and installed Big Sur over Catalina, keeping all of my data. System Preferences worked fine in Catalina.
The error describes “NSPrefPaneBundle supportedAppearance” - due to “Appearance” my first thought was to toggle Dark Mode from Control Centre, but that did not fix anything. I’ve restarted many times and continue to have this issue.
