See my Answer; I show exactly which file you need to delete (or rename)

psat has a settings.m file that is interfering with the use of MATLAB.
If I recall correctly you can rename the psat file and it will run correctly. psat uses it to store preferences but will run without it.

Give the command
which settings
You will get a response such as
C:\Program Files\MATLAB\R2020b\toolbox\psat\settings.m
showing a file under the psat installation directory.
Delete that file.
That will get you past that error.
You will probably not be able to run PSAT anyhow; you will probably get errors about
psatdomain not being a registered domain. see https://www.mathworks.com/matlabcentral/answers/595150-i-can-t-save-a-psat-file

Although deleting the settings command from PSAT solves this issue, I would rather suggest renaming it (e.g. to 'psat_settings.m'), and modifying the call to that file in line 231 from psat.m (version 2.1.11):
try
psat_settings()
catch
At least this solved the problem for me.
@Walter Roberson, Ok thanks very much Mr/ Roberson
I tried to delete the setting file, then rename it, but nothing happened.
then i get into internal error lines and put % before mentioned error lines but also nothing happened and error still existed, so finally i had to uninstall matlab 2021b and install it again.

If you are using psat, you can get rid of this problem by setting the path back to default. MATLAB>Home> Set Path> a dialogue box opens> default. Even if the command windows show error, using normal matlab will not be a problem and if you want to use psat again, you need to change the path through set path back to the psat folder.
