Xcode crashing when fetching team list

Question

So basically Xcode 6.1 is crashing whenever it's trying to get team list. From the general tab in the main screen, when trying to submit the app to iTunes, trying to validate the app.. whenever it tries to get team list, it crashes. It is working fine an hour ago but when we added some team members in the iTunes account for internal testing, it started crashing.

Any ideas?

Answer 1

I followed @cclogg's advice and saw that there was an expired account that was crashing. However, it wouldn't let me select the account without crashing XCode. I was only able to do this by selecting two accounts together and this prevented XCode from trying to fetch account information.

After that, I clicked on the minus button to delete both accounts. I figured it would be easier to re-add the second account. And now, the crashing problem is gone.
