We have a requirement to upgrade our website from php7.2 to php8.0
I upgrade the Laravel version to v8 which is the lowest version which support php8.1
After the upgrade most of the php8.1 related issues were fixed. But I got this Fatal error.

Fatal error: Uncaught ReflectionException: Class "blade.compiler" does not 
exist in /var/www/app/wp-content/plugins/xxx/vendor/illuminate/container/Container.php:877

You need to provide more details

How did you do this? What is your composer.json? What are the minimal reproduction steps?
