Just finished the Outbreak Mission (campaign mode) and when I watch the cinematic episodes between the missions (or start a new one), the game started crashing since I bought the StarCraft II: Campaign Collection at the end of last month.
And since I updated to the new patch 4.11.3 on Christmas Eve, not only the game, but the computer crashes forcing a restart!
I use an iMac (Retina 4K, 21.5-inch, 2017) with macOS Catalina 15.2
