Error during: Ensure Homebrew is installed

[Dante1349]

I have this issue on some mac machines, but i didn't find a good way to resolve it. I deleted the homebrew directory on my mac, but now i have problems during the cask installation because the casks are not registered within the new homebrew installation. Is there any solution to this. This came up during the lastest macOS updates.

I've got the same error:
