SC2 Editor crashes at launch M3 MacBook Air

I just got a new M3 MacBook Air, and I tried to run the editor. SC2 runs fine, but as soon as the editor tries to launch I get:

StarCraft II has encountered an error while initializing your videocard. Please try starting StarCraft II again, or restarting your machine. If the problem persists, for more information consult our support website at Blizzard Support.

I see multiple, closed, similar threads, but no resolutions. Can anyone help?
