Crashing, freezing, and stuttering after 8.3 [Intel GPUs]

I’m experiencing the same issue and wanted to share more details:

2017 MacBook Pro 13", Touch Bar, Intel Iris Plus 650, 3.1 GHz Core i5, 8GB DDR3, MacOS 10.15.3
Hardware tests: pass. Blizzard Client: updated. WoW: 8.3.0.33369.

Issue occurs during combat with any graphic setting. “Beachball” appears, game freezes, followed by computer crash and automatic restart.

Temporary fixes:

  1. During “beachball” command tab works after 5-10 seconds. Command-tab to return to game unfrozen. Issue will repeat after initiating any combat.
  2. After a crash, re-launching the game will not crash again unless ANY graphic setting is changed. However, in this state particle effects are completely disabled. Spells have no effects. This is only fixed by changing the graphic settings which again, lead to crashes during combat.
