This can be done without events, just override onBlockActivated in your block

Where are you getting zip files from? I would assume you are downloading CurseForge modpacks manually and dropping their zips into your mods folder, which is not how they work. If my assumption above is correct you should know that CurseForge modpacks do not contain the mods themselves, they instead have a manifest pointing to where the mods are on CurseForge's network, this manifest is intended to be read by the Twitch client which will then download the mods according to the manifest.

Do you set the registry name in your block's constructor? Is there a reason your block's constructor doesn't match Block's constructor?

Why would you post twice like that? Click on the Modpack -> Gear -> Repair profile
