During shutdown (when the little Fedora icon appears in the middle of the screen) hit F2 to see the generated DMESGs in realtime. This may help you to find the point where Fedora gets stuck.

I observed this "not shutting down"-behaviour sometimes when a new kernel comes via sudo dnf update. In my cases a subsequent shutdown or reboot lasts up to 30min, but it will finish after a certain period of time! Killing the machine during such a shutdown may not be a good idea, i once destroyed the whole installation doing this.

your advice is to reinstall the system?

Not now, this should be the last solution.
