Looks like - for whatever reason - your Exception handler is missing. It should be in app/Exceptions/Handler.php. If it's there, you might have an autoload issue.

If not, it looks like you unintentionally deleted it. You can find the source file (of version 7.x) here:

https://github.com/laravel/laravel/blob/7.x/app/Exceptions/Handler.php

Insert that file to your code.
