Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires yiisoft/yii-debug dev-master|dev-master#d5232f6fd5ec20381a6e874efdaf5e277339cf4e -> satisfiable by yiisoft/yii-debug[dev-master]. - yiisoft/yii-debug dev-master requires php ^8.1 -> your php version (8.0.30) does not satisfy that requirement.
