You need to remove or set the default value for the dark theme to false and add it to the entry for the theme you want to be default. Be sure that the file is correctly formatted as valid json or it will not work.

Thank you for your comment.
I understand what you're talking about, but unfortunately, it didn't work because I'm not very good at programming.
I tried using GPT chat to help, but it took me three hours, but unfortunately, it didn't work.
I composted the build file with a copied Web directory, and also tried accessing the system folder to replace config.json using GPT chat.
Unfortunately, it was all in vain.
It would be convenient if users could check a box in the web interface so we could choose and set a default theme.
Do you think it might be worth opening a case here https://github.com/jellyfin/jellyfin-web/issues and asking for such a checkbox to be added to the interface in the future?
Perhaps there are colleagues on the forum who use the synology/docker/jellyfin combination.
I'd be grateful if you could respond and tell me how to do this correctly.
Thanks everyone.
