I'm on a Windows 10 machine. I had a well functioning Matlab 2018a installed and then suddenly it stopped working. When I try to open Matlab, it shows up in my Task Manager but the software just doesn't open.
I uninstalled 2018a, downloaded and installed 2018b and activated it, but it still shows the same behavior.
Can someone please help me? I've wasted hours of effort on this and can't make it work.

It might be because MATLAB's prefdir is corrupted.
Please delete the following folders (previous prefdir)
  • C:\Users\YOUR_USER_NAME\AppData\Roaming\MathWorks\MATLAB\R2018a
  • C:\Users\YOUR_USER_NAME\AppData\Roaming\MathWorks\MATLAB\R2018a_licenses
  • C:\Users\YOUR_USER_NAME\AppData\Roaming\MathWorks\MATLAB\R2018b
  • C:\Users\YOUR_USER_NAME\AppData\Roaming\MathWorks\MATLAB\R2018b_licenses
and launch MATLAB R2018b again.

The default prefdir of MacOS is
/Users/$USER/Library/Application Support/MathWorks/MATLAB/<MATLAB Version>

These are some of the methods.
  1. Restart your computer and launch MATLAB again.
  2. Go to task manager and end the process if it is running without opening and displaying on the screen.
  3. Delete the temporary files
  4. Delete the AppData/Roaming/Mathworks/R20xxx.
All above listed ways could work but the 4th method is so effective.
That is it.
