Heya,
We've made a beta build for those, who experience game crashes after loading screen "connecting to". Initial tests show that the issue was fixed. This beta *might* address "Not Responding" hang, but it's more of a performance issue.
Anyway, beta is in a separate app branch. It will be merged with the default one after tests will show some results.
How to run beta
Please, report back if it solves a crash issue for you or not.
