Notification center not working on Big Sur
I have a 2018 15-inch MacBook Pro (2.6 GHz 6-Core Intel Core i7, 16 GB 2400 MHz DDR4) and ever since I installed Big Sur, my Notification Centre does not work. I though it might have been an update error so I waited for a few more updates (the latest one installed being 11.2.3 (20D91)) but still nothing. It works for a brief second when I turn the laptop on or reset it. And then afterwards nothing. When I look at it on the Activity Monitor, it says '(Not responding)'. And then I quit it or force quit it and then it works for <1 min and then it's back to square one.
Anyone have any insight as to what's going on and/or how to fix it?
Thank you in advance!
MacBook Pro 15″, macOS 11.2
