Cannot install WC3: Reforged on MacOS

For the life of me, I cannot install WC3: Reforged on my M1 Mac mini. 29% into the install, I received an BLZBNTAGT00000840 error code and then it stops installing, and changes to Update. Blizzard Support has been… less than helpful. I think it’s probably some kind of permissions issue with some of the WC3 files or or the Agent. Frustratingly, I was able to install on my M1 MacBook Air without doing anything special so I am officially stumped. Any ideas?

Hy - did you figure out any solution?

I found some posts here - but they didn’t work for me. Maybe you wanna give it a shot?
