Jellyfin 10.9 docker guide update fails

[cofulese]

Hi
I've just updated to the latest official docker image for jellyfin 10.9.
Whenever I try to run the guide update (schedules direct), I get this error:

Code:

[15:30:59] [ERR] [19] Emby.Server.Implementations.ScheduledTasks.TaskManager: Error executing Scheduled Task
System.UnauthorizedAccessException: Access to the path '/config/data/livetv' is denied.

I have verified permissions for the folder, by running docker exec -ti jellyfin /bin/bash and navigating to the folder, then writing new files, renaming existing files, and deleting existing files.

Any idea how I can resolve the issue please?

Many thanks
