I have had the same issue at the command line:
spctl --status
sudo spctl --status
% spctl --status
objc[1909]: Class SPExecutionPolicy is implemented in both /System/Library/PrivateFrameworks/SystemPolicy.framework/Versions/A/SystemPolicy and /usr/sbin/spctl. One of the two will be used. Which one is undefined.
objc[1909]: Class AppWrapper is implemented in both /System/Library/PrivateFrameworks/SystemPolicy.framework/Versions/A/SystemPolicy and /usr/sbin/spctl. One of the two will be used. Which one is undefined.
This is on a new machine with the latest version of BigSur 11.1 and all updates.
Thanks
