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:

Hi Khushal,

This error message seems to indicate an issue with the “startup.m” file, which is a user defined script executed at MATLAB startup. This file is usually located in the userpath folder, which can be found using the command

userpath

You can check if any recent changes were made to this file which could be causing the error, particularly any lines related to “qss_tb_library”. If possible, clear the “startup.m” file, restart MATLAB and see if the issue persists.

The error could also indicate the existence of a duplicate “startup.m” file. To locate all “startup.m” files, you can use the command

which startup -all

Try renaming any duplicate files, restart MATLAB and check if the error still comes up. For more information on the “startup” file, you can refer to the following documentation:

Hope this resolves the issue.
