Hi I have just been through and managed to get composer to upgrade.
That has given me two new problems:
I get Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.2.0".
That appears in the web browser and on the command line drush is giving me this :
The service "media_library_importer.service" has a dependency on a non-existent service "queue_ui.batch".
I have tried changing the PHP version in Cpanel between 8.1, 8.2 and 8.3 and I still get the white screen of death.
