Hallo.
beim Aufruf des Contao Managers einer ansonsten problemlos funktionierenden Website hat dieser automatisch updatet - dann bleibt er nach "Found Contao 4.9.9 (API version 2)" mit einem schwarzen Screen hängen:

Code:

PHP-Version munter durchprobiert: 7.3., 7.4, 8...
composer.lock gelöscht.

auch in der composer.json ist nichts ungewöhnliches:
