Crash in Online Challenge

Dear Support,

I can play offline games without problem

but when I try some online challenge, press download, choose fight, deploy my ships and press Fight–>then black screen and crash.

which version is this? (top right of main menu screen)
Is it all challenges or just certain ones?
Is this with challenges for maps you do not have (such as modded maps) or for maps you have not unlocked yet?

I was also having the same problem until I updated the game to the newest version of 1.24
