I was able to fix this issue by removing any space in the values in the .envfile e.g.:
我能够通过删除.env文件中值中的任何空格来解决这个问题，例如：
MAIL_PORT= 587
MAIL_FROM_NAME=ABC Medical
to:
到：
MAIL_PORT=587
MAIL_FROM_NAME=ABCMedical
Or by using quotes:
或者使用引号：
MAIL_PORT=587
MAIL_FROM_NAME="ABC Medical"

I got this error when passing values with spaces in .envwithout quotes, I fixed it by wrapping the values in quotes.
我在传递带空格.env而不带引号的值时遇到此错误，我通过将值括在引号中来修复它。

have you try
composer dump-autoload?
你试过
composer dump-autoload吗？
you might add a class without dump-autoload
你可以添加一个没有 dump-autoload 的类

Most common reasons I can think of for this error to occur are the following:
我能想到的导致此错误发生的最常见原因如下：
- Log class is called in a scope where it is not included with the USE statement.
- A config file contains (parse) errors, which in turn does not allow your application to find the Log class. Check the files loaded early on in Laravel such as app.php.
- Log 类在不包含在 USE 语句中的范围内被调用。
- 配置文件包含（解析）错误，这反过来又不允许您的应用程序找到 Log 类。检查 Laravel 中早期加载的文件，例如 app.php。
