I have linked my accounts, and have purchased the game. But I still dont see any beta to download not in my steam library and not in my rewards page, please help

I'm in the same boat. I have the closed beta badge and that is it. I even tried to unlink and relink my account a few times and nothing.

They put out an update on the game and removed the exe of the game, preventing people from playing it.

Same thing happened to me. Uninstalled it and tried to install it, but the file size was only 21bytes.
