v2.2.50 is no longer available for download from upstream. I've enquired as to the reason, will revert when I know more.

[gromgit]

From upstream:

After releasing version 2.2.50 for macOS, we identified a bug and removed the download. We have reverted it to the latest stable version, version 2.2.48.

I recommend updating the Homebrew version to 2.2.48 for now, until we release another stable version.
