I found two diffrent softlocks. They're both reversable by hitting Save & Quit or you can get out of them with Save & Quit but they're still there.
The first one is versus Marino, after you beat him up and you have your little conversation afterwards if you skip the convo with esc during the time you're holding the medalion over your head the game will softlock, it'll reward you the quest reward and you'll be able to go to the menu but you won't be able to move and you'll just stand there holding the medalion over your head.
Softlock Marino
In menu during Softlock
The other softlock is right after when you're going to your father at the manor with the medalion. After you activate the cutscene you can't make teleports out of the manor, but if you lay a teleport before you activate the cutscene in the room you'll be able to teleport out of the manor and this will ruin everything when you go back, the HQ office will be blocked by the guard but he still thinks it's during the cutscene.
Laying Teleport
Teleport after cutscene
Coming back to HQ after teleport
Guards confused yo
As I said both can be reverse by save & quit. The Marino one grants you the item even after you save & quit but the one in the HQ actually requires you to do the cutscenes again mostlikely because it doesn't save the states anywhere until you've accepted the quest to further the plot. There's also a similar one where you put a teleport infront of the Waltz door and when you come out you get teleported and the game softlocks, you don't get fairy and thus can't continue until you save & quit and do the cutscenes again.
