OpenRA won't open after closing

[Sleipnir]

Does it start and then crash, or not run at all?
If it crashes it will display a dialog saying "the game has crashed".

Could you paste the contents of ~/Library/Application Support/OpenRA/Logs/exception.log?

Run the Console app (Applications/Utilities/Console.app), and click "Show Log List" if the sidebar is hidden. Select "All Messages" and then type OpenRA into the search field on the top-right.

Copy any messages that it says here.
