 > 1. Apply the workaround in the link I provided above

 Hard-coding the stream wrappers is not the best solution. You could be
 breaking functionality that a plugin is relying on.

 > 2. Stop automatic updates by adding define( 'WP_AUTO_UPDATE_CORE', false
 ); to wp-config.php

 You should only do this if you remember to remove it later. Disabling auto
 updates is usually not a good option, especially since 4.9.7 is a security
 release, not just a bug fix release.

 > 3. Wait for a proper fix

 For those experiencing the issues, can you confirm whether the attached
 patch fixes your issues? I believe the issue actually stems from the call
 to `preg_match()`.
