I'm unable to access the home/envir​onment/set​tings window in freshly installed 2025a

I installed 2025a today. I select "Settings" (gear icon) from the Home/Environment menu. A window appears that is titled "Settings" launches, with "Help", "OK", "Cancel", and "Apply" buttons at the bottom. However, the content of the window is blank with a circle icon that has a revolving blue segment. I have let this try to load for over an hour with no change occurring.

I've tried closing MATLAB, renaming the C:\Users\username\AppData\Roaming\MathWorks\MATLAB\R2025a preferences folder, and re-launching MATLAB to have it create a new preferences folder. This did not fix the settings window problem.

You should directly contact Matlab's Technical Support:

Did you manage to fix it? Its occuring for me in MATLAB online too.

EDIT: I managed to fix the issue by following the steps described in 3. (reset session data) of this comment to another issue

Hi @John,

Here are some additional steps you can try to resolve the blank Settings window in MATLAB R2025a:

• MATLAB’s Settings window uses Java. If there’s a problem with the Java environment, UI elements may not load.In MATLAB Command Window, type the following command and make sure it reports a supported Java version.

version -java

• Try launching MATLAB with the "-nodesktop" and "-nosplash" options to see if the issue persists. Open Command Prompt and run the following command:

matlab -nodesktop -nosplash %open MATLAB
settings %open settings

• You can also try clean installation of MATLAB, and for that refer to the following MATLAB answer link: https://www.mathworks.com/matlabcentral/answers/131519-how-do-i-perform-a-clean-installation-of-matlab

Hope this helps!

I appreciate the suggestions. I have since tried them all without success.

Still no feedback from Support ? That's surprising.

Working with support. No resolution to report.
