matlab 2025a or b not starting

I have a fresh install of windows 11 on a laptop and I have not been able to get matlab 2025a or b to start. It keeps getting stuck at the splash screen. I have been able to run matlab using the -nodesktop switch but I'm not sure what to do next to figure out what the problem is. Can you help? Thanks!

Possibly a licensing file issue w/ new OS install/update as the update may have affected file paths.

The typical location is

%AppData%\MathWorks\MATLAB\<R20XXy>_licenses\ 

that might look something like

C:\Users\YourUser\AppData\Roaming\MathWorks\MATLAB\R2024b_licenses\

There should be a license file at that location. Or, look at the installation location and find where the license file is and the environment variable should point to that location.

You could use the -c startup flag to force MATLAB to point to a specific license file location if it isn't at the default.

MathWorks does support startup and licensing problems so if the above doesn't solve the problem, call Mathworks at <Product Support Page> info.
