Many files moved

Hello everyone!
For some months now I have been using the portable version of Anki [Version 2.1.30 (06a69c25)] (I have a company PC and I cannot install anything) for my university studies and I am enthusiastic about it.
I use a lot of the add-on “Image Occlusion Enhanced for Anki 21 alpha” with which I made several cards.

I usually use mainly the Android version to review the cards.

I noticed that as I went through the reviews, many cards appeared with a thumbnail instead of the correct image.
Running Tools-> Check Media results in many missing files and several unused files.
Inside the <> directory, the files are no longer present.
It seems they have been deleted.

I later found the missing files inside the directory <C:\Users\Luca\PortableApps\AnkiPortable>

I suppos it is a problem of synchronization with the DB on the WEB, for which the reviewed cards are then mistakenly written in the wrong directory.

I ask you if there is a configuration file that allows you to check where the files should be saved.

I attach Debug Info.

Thank you so much to anyone who can help me.
