Unable to log in to Launcher Tirify via Steam

[Молчаливый убийц]

This problem has persisted for many days, and even after updating the client to V66, it still exists.
I tried uninstalling and reinstalling the game, but it didn't work!

However, when I logged into the game and checked my stock, interestingly, there was nothing in it. (Here it refers to some skins I bought.)
