Hogwarts Legacy wasnt able to start because an error with the automatic backup of the savegames. When starting steam from terminal it showd some errors and so i tried to move the backup folder away from there and after this it worked again
But mangohud still shows that gamemode isnt running. So i searched a bit and it seems that gamemode IS running but mangohud just shows a wrong stat. With gamemoded -s i get the info that it os running. How can i get mangohud to work again correctly?
