Battle.net Launcher - Unable to install on macOS 15.2

I receive the error code: BLZBNTAGT00000840

I have tried all of the steps with no resolution.

I have gone as far as reformatting my entire Mac and trying this on a fresh install of MacOS.

Specs:
macOS Sequoia 15.2
Apple M3
16GB RAM

Steps:
Download the battle.net application from the battle.net website.
Double click the application.
Install almost finishes entirely, but errors out with the aforementioned error.

Zero issues with other applications.

Wrong forum.
