I recently upgraded my Valet and php7.4 installation using Homebrew, restarted Laravel Valet manually and only my projects with Symfony 4 stop working.
Note: Normally, when this happends I was able to resolve it by reinstalling Laravel Valet.
I can't see any error on logs, how can I debug this problem?
If you having problems serving Symfony projects after an brew upgrade or composer global update you must reset Laravel Valet with valet uninstall --force and make sure the Hombrew dependencies were removed and re installed correctly.
