On an M1 Mac with 12.6.5:

Homebrew fails with a 404:

$ brew install ioninja
Error: Download failed on Cask 'ioninja' with message: Failure while executing; `/usr/bin/env /opt/homebrew/Library/Homebrew/shims/shared/curl --disable --cookie /dev/null --globoff --show-error --user-agent Homebrew/4.0.17\ \(Macintosh\;\ arm64\ Mac\ OS\ X\ 12.6.5\)\ curl/7.87.0 --header Accept-Language:\ en --retry 3 --fail --location --silent --head --request GET https://tibbo.com/downloads/archive/ioninja/ioninja-5.3.2/ioninja-5.3.2-mac.tar.xz` exited with 22. Here's the output:
curl: (22) The requested URL returned error: 404

When installed from package, crashes at start because QT cannot be found:

Termination Reason:    Namespace DYLD, Code 1 Library missing
Library not loaded: '/opt/homebrew/*/QtNetwork.framework/Versions/5/QtNetwork'
Referenced from: '/Volumes/*/IO Ninja.app/Contents/MacOS/ioninja'

5.3.1 (Intel), installed from package, works fine on the same system.
