I just wanted to post a solution to this issue in case anyone else is using PHPStorm and experiences it.
What’s happening is that after the latest update to Local (5.7.5+4909) there is now a file that Local is using that is outside the WP installation directory. The default debug settings for PHPStorm have an option for “Force break at first line when a script is outside the project” that is enabled. You will need to disable this option in order to stop the breakpoint from happening on every page load when using XDebug in PHPStorm in the latest version of Local.
The full path to the options in PHPStorm is:
Languages & Frameworks -> PHP -> Debug ->Xdebug section
