    From your composer.json it is obvious that it is using Laravel version 5.4.*. You can find this [link](https://stackoverflow.com/questions/65218631/laravel-app-stopped-working-after-upgrading-to-php-8) useful – Ali Abbasov Jun 11 '21 at 12:42

  • Can you clarify what error are you getting after updating composer? – Ali Abbasov Jun 11 '21 at 13:55
  • Error : phpunit/phpunit[5.7.0, ..., 5.7.27] require php ^5.6 || ^7.0 -> your php version (8.0.1) does not satisfy that requirement. - Root composer.json requires phpunit/phpunit ~5.7 -> satisfiable by phpunit/phpunit[5.7.0, ..., 5.7.27]. – Gopalkrish Jun 11 '21 at 13:56
