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.

I have a similar issue:
Warning: Initializing MATLAB Graphics failed.
This indicates a potentially serious problem in your MATLAB setup, which should be resolved as
soon as possible. Error detected was:
MATLAB:getfield:InvalidType
Inputs must be strings, character vectors, or cell array of indices.

In matlab.graphics.internal.initialize (line 15)

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.
