Steamback desktop stopped saving games

[JustCryen]

Last save I have is from 5 months ago but I don't always use steamback while playing games.

The problem currently is with Hellblade: Senua's sacrifice, Steamback gives me an option to undo changes to this game but it does not save any new states of the game.
So it must be aware that the game stopped running but it does not add a new state of the game to the saved list.

This is the error thrown when running Steamback through the terminal:

ERROR:asyncio:Task exception was never retrieved
