Question

Laravel

On a working project, I ran php artisan config:cache, after that I got an error 500, the php artisan command displays the following

Answer 1

Try to "roll back" the optimized cache you created.
artisan
config:cache Create a cache file for faster configuration loading
config:clear Remove the configuration cache file
---
i.e. run php artisan config:clear
