Windows doesn't let my app copy a file to AppData

Hi, I created two new User accounts on Windows 10, one with Administrator rights and one without. In both I have run for the first time an app created with JUCE. For some reason it can’t copy a file to File::getSpecialLocation(File::userApplicationDataDirectory) and it fails without an error message.

I don’t have a problem with the account I am using normally and I have noticed the problem takes place when copying a file, not when creating/writing to it.

I’m using JUCE 7.0.5 and in Windows I’ve given permission to apps to write to the file system and I have disabled the “ransomware protection”.

Anybody can guess what I am missing?
