执行composer update后php artisan命令运行异常缓慢求助

执行composer update后，我的php artisan命令运行变得异常缓慢；但回退版本仅执行composer install时，命令运行完全正常。当前CLI的CPU占用约50%，完成一次php artisan命令需要30-40秒，而正常情况下最多只需要2秒。

我在composer update后已经按顺序尝试了以下命令：

• php artisan cache:clear
• php artisan config:clear
• php artisan route:clear
• php artisan view:clear
• php artisan clear-compiled
• composer dumpautoload

我的composer.json内容如下：
