you will need to reinstall. rebasing from 1 DE to another is NOT RECOMMENDED by us or upstream(fedora) because the different DE configs are known to cause issues
Hm, weird. When selecting beta from the "OS Update Channel" menu in gamemode and restarting, the menu changes back to stable, and the OS -information still says fedora 39. But, now bluetooth is working again. I had to re-pair the bluetooth-controller i had, but other than that, it seems like its fixed now...
