Minecraft Launcher can't open due to missing launcher core (Mac)

A while back I tried downloading Minecraft onto my mac but found trouble logging in for whatever reason. Nothing worked so I attempted deleting everything on my computer related to Minecraft. Redownloading the launcher now causes an error message stating that the Launcher Core didn't exist.

I tried downloading a core to put in the launcher folder, but that didn't work (I got the core from here: "https://pypi.org/project/minecraft-launcher-core/").

Attempting to delete the minecraft folder and launcher folder from the application support folder and redownloading the launcher only brings them back without the launcher core.
