I get the following error running the example code:
>> worldmap world
Error using referenceSphere
The specified superclass 'map.geodesy.Sphere' contains a parse error, cannot be found on MATLAB's search path, or
is shadowed by another file with the same name.
Error in regionmap (line 51)
e = referenceSphere('earth','meters');
Error in worldmap (line 122)
ax = regionmap(mfilename, varargin);

Can you show us what the following commands display?
which -all worldmap
which -all regionmap
which -all referenceSphere
which -all map.geodesy.Sphere

In R2020a,
which -all map.geodesy.Sphere
will return the following file.
MATLAB_INSTALL\toolbox\shared\mapgeodesy\+map\+geodesy\Sphere.m % map.geodesy.Sphere constructor
toolbox\shared\mapgeodesy folder is created when Mapping Toolbox is installed.
Please confirm toolbox\shared\mapgeodesy\+map\+geodesy\Sphere.m does exist, if it exists, it seems the foloder was removed fomr MATLAB search paht.
So, you will need to do addpath
addpath('C:\Program Files\MATLAB\R2020a\toolbox\shared\mapgeodesy')
savepath
Or reset MATLAB search path to the initial conditions.
restoredefaultpath
If toolbox\shared\mapgeodesy folder does not exist, there might something wrong in your installation. So you need to install Mapping Toolbox again.
