Hi,
The last week I've upgraded my Mac Mini (2018) to Big Sur and the Notification Center started crashing once per second:
Nov 26 10:17:17 ---- NotificationCenter[36862]: objc[36862]: Class NCCAFenceWrapper is implemented in both /System/Library/PrivateFrameworks/NotificationCenterUI.framework/Versions/A/NotificationCenterUI and /System/Library/CoreServices/NotificationCenter.app/Contents/MacOS/NotificationCenter. One of the two will be used. Which one is undefined.

One of the two will be used. Which one is undefined.
Nov 26 10:17:17 ---- com.apple.xpc.launchd[1] (com.apple.notificationcenterui.agent[36862]): Service exited due to SIGILL | sent by exc handler[36862]
Nov 26 10:17:17 ---- com.apple.xpc.launchd[1] (com.apple.notificationcenterui.agent): Service only ran for 0 seconds. Pushing respawn out by 1 seconds.
I've lots of crashes in the console and I cannot run the Notification Center from the Terminal:
/System/Library/CoreServices/NotificationCenter.app/Contents/MacOS/NotificationCenter
objc[34799]: Class NCCAFenceWrapper is implemented in both /System/Library/PrivateFrameworks/NotificationCenterUI.framework/Versions/A/NotificationCenterUI and /System/Library/CoreServices/NotificationCenter.app/Contents/MacOS/NotificationCenter. One of the two will be used. Which one is undefined.

I've used the Feedback Application to report this but no one seams to look at it.

Anyone is having problems with the Notification Center in Big Sur too?
Many thanks
