Bug when starting SinglePlayer or Learn to play game

[Maza]

Hey, all.

Got this weird bug when I'm trying to start single player or learn to play games - progress bar gets stuck shortly after beginning to load, see screenshot.
Logs show

Windows updates, GPU drivers are up-to-date.

Any ideas how to fix this?

Thanks.
