This may be futile here, but I'll give it a go before bugging TMW Tech Support...
I'll begin with the caveat I really don't follow how IT has set up default user locations, but there's a path to a network drive that looks something like
[\\mfs0.institutioninitials.edu\redirectempdocs\firstname.lastname\My Documents]
Under this I have subdirectory MATLAB and
4/18/2019 15:20 <DIR> .
4/18/2019 15:20 <DIR> ..
12/12/2018 16:38 <DIR> CAMPAIGN
5/15/2019 15:58 <DIR> RESTRICTED
12/17/2018 12:46 <DIR> XXXX_Foundation
5/15/2019 14:11 <DIR> utils
6/23/2020 16:42 <DIR> work
and the startup path from the preferences settings leaves me in the In the MATLAB work subdirectory on startup. That's all well and good.
The problem am having comes that at a prior time I mapped a drive to the former network drive "\\mfs0.institutioninitials.edu\firstname.lastname\My Documents" for convenience so could use just "Z:\CAMPAIGN\datafileXYZ.mat" instead of the full name. At some point IT reconfigured the network drives and that mapping was broken...I have now fixed the registry references to the previous mapping so Windows/File Explorer doesn't have the broken map any longer, but somewhere in the MATLAB startup there's still a reference to the above paths referring to the no longer extant Z: drive --

still shows up on the initial screen when starting MATLAB.
I can't for the life of me figure out where this is squirreled away to kill those references to Z:
Anybody here know the bowels of the install process well enough to have a clue where to look?
