launchd @ 100% CPU or more after update to 10.15.4
I updated my Mac mini (2018) to 10.15.4 today, and now launchd is consuming 100% of CPU according to Activity Monitor. Console shows that it is continuously failing to launch diskutil, as it is searching in /usr/sbin/diskutil, and apparently it no longer has access to that location. /usr/sbin/diskutil is certainly there, has read and execute permissions, and I can manually start Disk Utilities from Finder. How do I fix this?
% ls -l /usr/sbin/diskutil
-rwxr-xr-x 1 root wheel 532080 Mar 17 08:42 /usr/sbin/diskutil
From console:
