Dependency analyzer refuses to work

I have tried to run the Dependency Analyzer from the Apps tab countless times and it has only worked once. I didn't do anything differently from the previous and next attempt, it just randomly worked. I have tried selecting individual files and whole folders. It shows it's analyzing each item, then throws an error and says it's "Updating the graph" forever and all you can do is close the window.

I've tried reinstalling and updating Matlab, running as administrator, trying different file types, etc. all to no avail.

If you don't mind losing your settings, try closing MATLAB and deleting your preferences directory. Oftentimes when MATLAB gets repeatedly stuck on something like this, the cause is stored in the preferences directory:

In case it is a preferences problem, you might want to make a backup copy of the preferences folder somewhere other than prefdir before deleting the preferences folder for that release. That way, if it resolves the problem, you could zip the back up copy and send it to Technical Support so they can investigate what in the preferences folder caused the error.

@Stephen23 This did not solve it. I'm working on a pretty fresh installation of MATLAB as well. I only selected to install MATLAB and Simulink to start. Do you know if I need any other add-ons to get the Dependency Analyzer to work?

I've tried the dependency Analyzer a few times with the same result. The Dependency Analyzes really shouldn't break MATLAB forcing me to kill and restart it.

I have the EXACT same problem. Never had any trouble with 2025a and earlier. This is a very helpful app so please fix :-)

"This is a very helpful app so please fix :-)"

This is just a forum of volunteers, we cannot "fix" anything.

Here is the correct place to request TMW support, to report bugs, etc:

Do you really need all the features of the app environment for what you are doing? You can analyze dependencies programmatically with matlab.codetools.requiredFilesAndProducts. If nothing else, running it might help determine if the problem is in your dependency tree or in the app itself.

Yes I do at least - the app is very helpful - I would like it to work. A bunch of people are having this issue now since 2025b. I have two separate projects and they both throw this exact error now.
