Cannot access system preferences after upgrading to Big Sur
I have just purchased a 13" MacBook Pro with preinstalled with macOS Catalina. I had no issues accessing the system preference but after upgrading to Mac OS Big Sur 11.1, I cannot access it even though I am the only user on this Mac and have admin access. I have tried clearing my disk and reinstalling factory settings which got macOS Catalina back. Checked the system preference and was able to access it, then upgraded to macOS Big Sure and the problem is back. I cannot access system preferences for changes.
Has anyone else had similar issues? Any suggestions? I appreciate any help I can get.
