"Utilities" is the title towards the bottom of the Process panel ("Available Process menus" - the list of processes to use); it should show from left to right 'SOUND INFO", "SPECTRAL INFO", "PITCH INFO" and "HOUSEKEEP". If the last is not shown, that means the program "houskeep" (or "houskeep.exe" on the PC) needs renaming. It is used by the CHANNELS process.
If it is shown, the problem lies elsewhere. At the risk of stating the obvious: if channel extraction is the first step in an Instrument, it expects at least a stereo infile, and will likely fail if the infile is mono.
There should be no need to reinstall Mojave - I am sure this is only a CDP/Soundloom issue.
