Wouldn’t think the #bug-report was fitting for this.
If you’re game is currently crashing change your language pack: https://twitter.com/BlizzardCS
It’s known and worked on so it’s recommended to not send it in the #bug-report subforum due to it overflowing it eventually.
Thanks for reading and i hope i have helped you!
From what I have been seeing, a faster option may actually be to Scan and Repair.
If all else fails, uninstalling and reinstalling will definitely fix the issue.
There has been a crowded post within the #bug-report They’ve tried but it wasn’t a fix as i suggested it. (Link to post: Game crashes at hero select after the patch)
Even reinstallment didn’t work according to them. If possible you should link the posts relating to them since i think this is because of the new patch.
