Amazon Music app won't launch Recently bought a new Macbook Pro to replace an older Air. Everything is working great except for the Amazon Music app. It downloads and installs just fine, but when I try to launch it using Spotlight, double-clicking in Finder or right-click + "Open" in Finder...nothing happens. The system log reports that:

com.apple.xpc.launchd[1] (com.amazon.music.87788[14329]): Service exited with abnormal code: 1


Not very helpful. I've tinkered with the Security &amp; Privacy settings (i.e. "Allow apps downloaded from"), but that changed nothing. I've tried uninstalling the app and reinstalling it via Homebrew Cask. Nothing. I've tried un/re-installing the app various ways multiple times. Nothing.

The interesting part, and perhaps a glimmer of hope, is that if I flip over to the Guest user, I can open the app just fine.

Anyone have any idea what might be going on with my user account that would be impacting my ability to launch a particular application?
I just experienced the same symptoms. I resolved it by deleting ~/Library/Application Support/Amazon Music. The only file in that directory was a file called i18nUpgrade.txt with the contents Upgrade to i18n build.
