I have a roughly 1in 5 chance the game launches properly, very rarely does the game properly crash. Instead it hangs up on sign in. Usually at "downloading latest server configuration" occasionally earlier in the sequence at "connecting to back end". This happens both before and after cache clears, router reboots don't seem to help or hurt one way or the other. Using an Xbox One (no x/s series or otherwise, terabyte model run). I assume this is part of the already known xbox sign in issues, but adding my bit just in case.
Thanks for the info - I'm very hopeful that precisely this patch will help you with your sign in issue, but we're continuing to spend time investigating it!
