PermissionError: [WinError 5] Access is denied ... \AppData\\Local\\Temp\\

[1v4n0]

Hello, can't convert between epub and azw3. I get the following error.
No antivirus is running.

(Some words are in Italian, but the meaning should be clear anyway. It just says "conversion error. Couldn't convert", and at the end "Access denied".

Spoiler:

calibre, version 7.0.0 (win32, embedded-python: True)
Errore di conversione: Non riuscita: Converti libro 1 di 1 (Addio Anatolia)

See ==>> calibre [FAQ] I am getting a “Permission Denied” error?

You might want to consider giving calibre a dedicated Temp folder, see CALIBRE_TEMP_DIR ==>> Environment variables
