Graphics device is not available at this time, Please try starting Starcraft again or restarting your machine If the prblem persists, for more information conult our website.
I have restarted, reinstalled on another drive and updated graphics driver. All of other games work with no issues including all other Blizzard games
i have encountered that issue. in order to solve it however, i need to know more about your specs. primarily your gpu and operating system. that is because the problem is gpu related.
I have the same issue.
Windows 11 Pro Version 23H2. OS Build 22631.4460
13th Gen Intel Core i9-13900H 2.60 GHz
NVidia GeForce RTX 470 Laptop GPU
the game usually defaults to direct 3d 9 which your cpu is not compatible with. it is also badly optimised. in your starcraft 2 settings folder in your documents folder, there is a variables.txt file. there you can change it. GraphicsApi=Direct3D11
change it so that it looks like i posted.
