How to Fix the Warzone 2.0 Not Available Error
A lot of players are unable to launch Warzone 2.0 and their systems seemingly do nothing after clicking the Play button. There could be multiple reasons leading to the issue.

A quick system requirement check should help you find out if you can run Warzone 2.0 or not. If you do meet the system requirements here are some solutions that you can try.
Warzone 2.0 Not Launching: How to Fix
An ongoing bug is preventing players from queuing into Warzone games or even launching the game itself. If you are on Steam you can verify that the game's files are installed correctly on the computer.
Restart your computer and launch Steam
Next, you can either right-click the game in your Library or click the gear icon from the game's Library page on the far right
From the drop-down menu, select Properties...
Select the Local Files tab and click the “Verify integrity of game files” button
Steam will verify the game's files - this process may take several minutes
After completion, if you get the “One or more files may fail to verify” error, this is normal for most Steam games. The files that fail to verify are local configuration files that should not be replaced as part of this process. You can safely ignore this message.
Do not run the verification process while performing other system-intensive processes, such as defragmenting your hard drive or scanning for viruses. Do not run this process for multiple games at the same time.
If you are on Battle.net:
Open the Battle.net desktop app
Click on the Call of Duty: Warzone 2.0 icon in the Games menu
Click the cog wheel next to the Play button and choose the Scan and Repair option
If you are still unable to run the game, you should reach out to Activision’s support channel.
