First, attempt to make sure the "mupadmex.mexw64" file is present on the system. The file path will be provided in the error message in MATLAB.

Make sure your account has permissions to read and execute this file.

If the file is present and you have read and execute permissions, the problem may be related to a false detection from an antivirus program. Please check your antivirus software to see if there have been any files quarantined from your MATLAB installation. If there are files from your MATLAB installation directory that have been quarantined, please restore them.

Then, you may need to create an exception in your antivirus program for the MATLAB installation folder and its subfolders.
