Not today. But yes, I was "lucky" to win three keys sometime in the last two weeks. One of them is not working. 1 of 3.
I actually think (I'm not sure) this is the first non-working key I've got, and I've won this game seven times or more.
And if you just cross your fingers among the reports of won and non-working keys, it turns out somewhere like this, as for me it is up to 1/3 (when counting, do not forget about the error in the name of the key and the game itself in Steam).
This is still a very bad statistic, I would avoid such keys by the tenth road in all kinds of exchanges and raffles, but still, they are not almost all non-working. Of course, all these reports and statistics are not objective in any way.
Do you have your own accounting method?
