Whispering a friend who is playing Cold War instantly crashes their game

I was playing Cold War with 2 other friends, while the other friend is playing WoW. The friend playing WoW whispered me and the other friend with me, and it both instantly crashed our games. I tested it again, loading into the MP menu and asked him to whisper me, and it again crashed my game. I don’t know if it’s a bug with how Cold War is trying to process the whisper, or if it’s a bug with battle.net’s chat directly, but all I know is that it started recently and that it is consistent.
