Since updating to Drupal 8.3, I am seeing the following messages in the (PHP) error_log file on my hosting provider...

As a result of this (I think, given that it says 'PHP Request Shutdown') I cannot any longer get to the Modules page (http://drupal10.local/admin/modules) and see a 500 error.
My settings.php and my settings.local.php have been a round a while, is there something that I need to change there that relates to assertions?
Oddly, I CAN get to the Modules page on my local (Windows) development version which is allegedly using exactly the same version of Drupal (10.3) and PHP 8.3.x
Thank you

📌 Remove mentions of assert.active from .htaccess Needs work
Make sure you don't have assert.active set anywhere, including php.ini
Please check your PHP settings, eg in your PHP.ini see https://www.php.net/manual/en/outcontrol.configuration.php#ini.output-bu...
