Problem installing game [has an answer] (Counter-Strike: Global Offensive)

In general, 2 days ago I decided to reinstall the cs (there was a reason for that) and now I don’t know what to do. When the download is 100% complete, the installation begins, and after that the game requires an update. If you click update, then again the download is 100%, installation and again requires an update, and so on in an endless circle. If you click "Play" through the library, then the installation is in progress, then the error "update files were damaged." I downloaded the game again, unsuccessfully. I completely deleted the game and steam (I also cleaned the registry) - it did not help. I probably googled everything I could. Steam and the game are installed on the same hard drive, the installation path is all in English. In the common folder in the cs folder there is only one file "installscript.vdf", and in the "downloading 730" folder the entire game directory is located, but Steam refuses to accept it. I tried to manually put the game from the "downloading" folder into common, Steam starts checking existing files and again stupidly downloads again. I tried to download the game on another computer, everything downloaded and works quietly, I transferred the working directory to my computer, and again the same problem, Steam either does not accept files and downloads again, or tries to download somewhere around 1GB, and again, in fact, the same problem , requires an update that won't load.
I do not know what to do. I hope someone can help me, because I really want to play, and the error itself is somehow strange.
PS other games are downloaded and installed without problems. During installation, I turned off the antivirus and firewall, did not help. I also noticed that during the download, the download itself often goes into the queue, that is, the game is downloaded then goes into the queue with the message "the download is scheduled for such and such a time" and you have to resume it.
