--- Comment #5 from Maciej Stanczew maciej.stanczew+b@gmail.com --- I am using Staging 5.22 with f257f37b92041fc718de04aa83ec3139b748ffa2, and I did experience the issue on this build. But, for me the reproduction really seems to be completely random.
Just 2 days ago I had what seemed to be 100% reproduction. Either immediately at launch, or after a couple of minutes, Battle.net would crash. This was during updating the game -- maybe it's related somehow.
I gathered logs, then reverted to Staging 5.21; launched Battle.net, and had it running for over 2 hours without any crashes. I then updated back to 5.22 + f257f37b92041fc718de04aa83ec3139b748ffa2, and… also have not seen any crashes since then.
