**I use Magento EE 2.3.1.
In my development environnement, I setup this module to track some bug in my Magento, When I finish, I remove this module with composer. Everything run well, after that when I make composer update or bin/magento setup:upgrade or bin/magento setup:di:compile I got this error:**
`In ErrorHandler.php line 61:
Warning: include_once(Smile/DebugToolbar/DB/Profiler.php): failed to open stream: No such file or directory in /app/vendor/magento/zendframework1/library/Zend/Loader.php on line 134
`
Now in the browser, I got this :
