Sharpening (Elden Ring)

Good day. There was a bug that severely breaks the game. I have already found a lot of Blacksmith Stones in the game. There are 5 of them in the inventory, in the chest you can’t see them at all, although there should be more than 10. The fact is that at the beginning of the game I already managed to sharpen a couple of weapons by +1. Now I came to the blacksmith, and the sharpening interface shows 0 stones, although they are available. Who has experienced this? Is a solution possible?
