Your project works for me.
Maybe there is an issue with the Russian translation?
Did you try the English version?

Hello, Pablo! Indeed, this error does not appear on the English version. There was no such problem before... Thanks.

The Russian translation has not been updated yet for version 17.2
This translation is made by another user, usually it take a few days before the Russian update is available.
I have no control over this.
