I see that there are locked threads about this from 2019, 2020 and 2021, but has there been any development here? I just 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 http://blizzard.com/support.”
It mentions the video card as a problem, could that have something to do with the OpenGL3/Metal switch that was made when going from intel to M1? That the editor is still trying to use OpenGL3?
