Warning: Initializing MATLAB Graphics failed

I recently upgraded matlab2024a, but as soon as I open the software I get the following warning message :

Warning: Failed to initialize MATLAB graphics.

This indicates that there may be a serious problem in your MATLAB setup that should be resolved as soon as possible. The error detected is: MATLAB:sum:wrongInput

MATLAB:sum:wrongInput

Invalid data type. The first parameter must be a numeric or logical value.

Try reinstalling MATLAB.

If that does not help, then contact Mathworks for free installation support.

I tried reinstalling it again, but it still shows this warning, but I don't have any problems running the program, is this bug a problem with matlab2024a?

Hi @Zhang san,

The issue may be resolved by running the following commands from MATLAB Command Window:

>>> restoredefaultpath
>>> rehash toolboxcache
>>> savepath

Restart MATLAB after this and see if that resolves the warning messages.

Feel free to reach out if you have any queries.
