After pressing “PLAY” button, my game just wont start.
After pressing it mulltiple times, i get an error code -
the CAS system was unable to initialize.
Anyone else having same issue, and could fix it?

I get the same thing. I’ve tried all of the steps on https://us.battle.net/support/en/article/13934 but no luck. Only started happening since the pre-patch went live.
Full Error:
"The CAS system was unable to initialize: Unable to initialize CAS from build info file. Code version does not match .build.info.
Unable to initialize CAS from patch service: provided version info string(s). VersionInfo:eu. CDNinfo: eu
Hoping this can be fixed without a re-install. Not even sure if that will work?

I got the same problem and solved with these steps:
-Modify the Config.wtf adding/modifying the lines
SET playIntroMovie “10”
SET gxApi “D3D12”
-Clear the nvidia cache folders (DXCache and GLCache in the path C:\Users<>\AppData\Local\NVIDIA
Watchout for duplicate lines in the Config.wtf, otherwise the value will be overridden by the last one.
(credits to the USA tech forum for the Config.wtf part)
Hmm, i do NOT have SET gxApi line in the config at all ?!
Please do read this thread;

It says “Page Not Found” for me.
Same/Similar issue here. But I found out, that I just need to wait.
Press play button, wait for 3-4 minutes and then game starts for me :).
