Warning: Executing startup failed in matlabrc. This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected

I have installed R2016a version without having any problem. But for R2021a and R2021b, I am getting this error as soon as I open Matlab

Warning: Executing startup failed in matlabrc.
This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as
possible.  Error detected was:
Default calibration file does not exist.

Does anyone have any Idea to solve this issue?

Thanks in advance:)

See if https://www.mathworks.com/matlabcentral/answers/494866-warning-executing-startup-failed-in-matlabrc-this-indicates-a-potentially-serious-problem-in-your?s_tid=answers_rc1-1_p1_MLT gives any satisfaction.

If that doesn't solve the problem, MathWorks supports installation/startup issues so contact them Monday AM.

Hello,

This error message may indicate an issue with your 'startup.m' file. This file is located in $MATLAB\toolbox\local (where $MATLAB is the MATLAB installation directory). Check if any recent changes were made to this file that could be causing the error.

This error message may also indicate the existence of a duplicate 'startup.m' file. Execute the following command to locate all 'startup.m' files:

>> which -all startup.m

Rename any incorrect file, and restart MATLAB. Check to see if the issue persists.

If the issue persists, temporarily rename your 'startup.m' file and restart MATLAB. Again, check to see if the warning message is still generated.
