I completed all the missions but all my data was deleted and the game seems to have restarted.

However, the rewards provided by the game remain in my inventory.

To explain this situation, I completed all the tasks until the last mission and started doing the last mission one by one. I completed the day 7 mission and finished the course. Then the game ran into a bug and so I quit the game. Later, when I entered the game again, everything was reset.

I did a few tasks (as in the picture) thinking maybe it would get better, but there was no change.
