Unrecognized function when starting brainstorm

After a few days of using brainstorm I can't start it anymore. It shows me this :

What can I do ?

I have never seen this...
Maybe try deleting the brainstorm3 folder and downloading a new one from the website.

I did it already and I did the same for matlab but nothing changed.

This error is reported here in different contexts:

You best guess is to delete the temporary folder:
C:\Users\[username]\AppData\Local\Temp\[username]\mcrCache[version]

If the error keeps on coming back, the second link proposes a solution for a more permanent solution, by setting manually the environment variable MCR_CACHE_ROOT.

It works after deleting the temporary folder. Thank you.
