I like the content server and also to use the "read" option, that works good for books like epub.
But I would like to use it also with Comics in CBZ or CBR. But this formats always display an error, that is not dependent on the Browser I use (Tested with samsung Internet and Chrome on Android and with Firefox and Chrome on PC Win11).
Is this something only my instance has or is it a general problem?

Example for the error :

Erstellen der Leseansicht des Buchs fehlgeschlagen
Konnte Aria nicht öffnen. Beim Bearbeiten des Buchs ist ein Fehler aufgetreten, clicke "Zeige Details" für mehr Informationen
Traceback (most recent call last):
File "calibre\srv\books.py", line 127, in job_done
PermissionError: [WinError 32] Der Prozess kann nicht auf die Datei zugreifen, da sie von einem anderen Prozess verwendet wird: '\\\\?\\C:\\Users\\andre\\AppData\\Local\\calibre-cache\\srvb\\s\\6s7yxa0x' -> '\\\\?\\C:\\Users\\andre\\AppData\\Local\\calibre-cache\\srvb\\f\\c2b92f2c0a8098e8507cc4bd16ea8cf07c 6a087d'

My translation: The process can not access the file, since it is used by an other process.

BTW. The download of the files and opening in an external bookviewer works fine.
