Server Error (500)

Hello, my website with django works very well except the admin page, I get a 505 error, I looked at the logs, and it would be because I don't have the dark_mode.css file, I looked, and it is not there in fact, so I deleted my static files, and re-executed the command "python collectsatic" but it still doesn't work, anyone have an idea where this could be coming from?

Have a look at this help page.
